- Опубліковано 19 тра 2024
- Paul Andersen explains the process of photosynthesis by which plants and algae can convert carbon dioxide into useable sugar. He begins with a brief description of the chloroplast. He describes the major pigments in a plant (like chlorophyll a and b). He then describes both the light reaction and the Calvin cycle. He finishes with a discussion of photorespiration and strategies for avoiding this problem evolved in CAM and C4 plants.

Thumbs up if you watch this the day before a biology test...
+Gallade6349 more like the day of, my exam is in 2 hours
I have my biology final tomorrow
+gymnastdancerstuff same
Tomorrow ! Lmao
Tmr damnit
It's always amazed me how scientists are able to discover these things on such a microscopic level
god bless the curious
He's so talented at explaining things. Thanks for helping millions of people on UA-cam as opposed to helping a smaller majority as a teacher in high school.
You are a trillion dollar teacher. Thanks for that.
:D
I agree! I am studying to become a teacher. He is a true inspiration!
But nobody can explain the obvious problem with this theory. CO2 is currently at around 450ppm in the atmosphere, less than 0.005% concentration, which is practically zero. Now compare to humans who breath oxygen at 20% (250,000 times higher concentration!!!), with our lungs, having the surface area of a football field!!! And yet we still need to breath in and out all the time to get enough oxygen. Plants don't even have lungs to cycle the air, nor blood circulation to carry it around. Can plants absorb any significant amount of CO2 to make any difference? Obviously not!!! The mainstream photosynthesis theory looks quite absurd, doesn't it? Because it is, and whoever made that shit up is laughing at you! So since the scientific community is a paid for, freak show, what else have they lied to you about? Scary ah? Well, I salute your bravery for reading this far, but don't stop here, you live in a faked reality, and you will need much more courage to make it out into the light! Fear not my child, God is with every earnest and sincere truth seeker, His Holy Spirit will guide each one in the most noble quest for the truth, amen!
"Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life." - John 8:12
Dude, don't talk about things from your square brain
Did you search for it at all?
The small percentage of CO2 in the air because originally the plant performs photosynthesis at the same speed as we inhale the oxygen that this plant mounts, so the percentage remains small
If we cut down half of the world's trees, the percentage of carbon dioxide would rise, just as you dream
Enough to suffocate half of the world's population and satisfy your absurd petty hypocrisy
@@TheFightingSheep go learn how plants even function u
hypster
They couldn't just stop with "Plants make oxygen" like we learned in third grade, could they?
Highschool.....
ikr
lol, a girl in my ap bio class said the same thing
+Jay Thermer Just wait until you get into college biochemistry. This stuff is child's play
Austin Cushing Hahahahaha. No.
+Austin Cushing Super Relate! hahaha it was easy in highschool :(
Better understanding than CrashCorse
Omfg hell yeah
The thing I hate about Crash Course Biology is it's lack of detail. They obviously have better animations (they have more money) but Mr. Andersen's videos are much higher quality.
so true
with Mr. Anderson's videos he actually keeps me interested, plus a full understanding. CrashCourse tries to somewhat make the subject "fun"/"funny" and it's really irritating. Like -_- really?
i like this video more for the light reactions but i actually do like the crash course one better for the calvin cycle. if you put them both together, they build off of each other and they are both great!
If I could only stay awake through the entire video.......
When all the thumb downs are from all the ap bio teachers that couldn't teach it better than him...
lmao
lol
Oooooooooooh!!!
Honestly. My teacher is the most monotone man on planet Earth
True
Shout out to everyone here because of the AP Bio exam and good luck!
u look beautiful...can I hv your number
^ 😂😂😂😂😂😂
+babyriri01 dam you look just as beautiful , can I have your number ?
+grace daugherty I'm having an AP bio exam tomorrow and I'm screwed.
My final is this Friday day! And good luck on your exam
Finally someone that is translating what a textbook teaches us.
thank you.
lmao ikr XD
It takes some kind of talent to be able to explain this concept so clearly and effectively while having a laid back attitude within 15 minutes whereas other teachers can't even convey this message after hours of lectures.
I wish you would be my biology teacher lol
Manny Guirguis my teacher just read the power points that most of the class can't understand
Manny Guirguis it sucks
+Mark Fedin he is mine (technically)
+Mark Fedin same, or we just do one lab without much explanation and then we have an entire test lmao
My ap bio teacher teaches similar to him now I see where she comes from
You and CrashCourse, man. My Bio professors have been lecturing for the past two weeks, and it's done nothing for me. You two? I'm not so scared for my exam tomorrow. Thank you. Like, I can't express the correct amount of gratitude I have.
Crash course is a legend
if anyone needs simple steps of photosynthesis...
1. light comes in
2. the light powers electrons through etc
3. those electrons go through proteins
4. these electrons pump protons
5. the electrons go through atp synthase
6. the electrons make atp
AT OR NEAR THE SAME TIME
1.water comes in
2. water splits into hydrogen and oxygen
3. oxygen diffuses
4. hydrogen ions are used to make energy
LATER IN THE CALVIN CYCLE
1. ATP and NADPH are there partying it up
2. 1 carbon molecule fuses with 5 rubisco
3. This compound mixes with ATP to form G3P
4. G3P makes rubisco and the cycle starts over
:)
Thanks Dude!
thank u!
They call the hydrogen by ”electron”. Don't they?!
Abodz Nope. Hydrogen is referred to as proton. electon is another product from splitting water.
Tianbo Sui I got it. Too much thank
I heard you won teacher of the year a couple years ago. Congratulations! Also, thanks so much for the great learning/teaching resource you provide to all of us science students and our teachers.
congratilations!!
In 12 minutes and 26 seconds, you have taught me everything I needed to know compared to my enriched bio teacher who taught this to us in 2 weeks. Thank you so much!
I wish this guy was my biology teacher. I learn more from him than I have in any of my biology lectures.
I know you commented this 6 years ago, but my teacher legit uses his videos to teach us...
You literally sumarized a whole chapter in my textbook in twelve minutes!! THANK YOU SOOOOO MUCHHHH!!!
Okay, I'm going to watch it five more times and then I'll hopefully understand...
+Simon Mikulstikova Dude you're clearly aren't smart or science ain't your favorite subject :(
Wyatt Sutton fix your grammar before you judge her intelligence
@Bad Beach Sorry dude I should've thought
@Simon Mikulstikova Sorry bro...do what you want
Ignore that first comment. I have had to do the same and science is the degree I am working on. To really grasp you need a multitude of subjects, definitely starting with chemistry. Without that foundation a lot of the terminology can be hard such as protons and ions. It makes you smart when you set out to try to learn more.
@@badddbeachhh409 white knight
You are a truly gifted teacher! Slow, step by step breakdown, well illustrated and with good cross-reference and a fair amount of redundancy. Great pace. Thank you!!!
You are a Biology god, I worship your videos, thank you for helping me ace my midterm, I love you.
When your bio teacher actually tells you to watch these videos instead of teaching it himself. Honestly tho this helps so much more
Watching this for my AP bio exam tomorrow. Wish me luck.
Same
+Callie Perkins me too!!
MinerMovie I guess we're all in this together
how did you do
i got a 3 :/
Nice, short & concise, not drawn out & boring. Thank you.
The only way I'm surviving in ap bio right now is because of your videos. THANK YOU SO MUCH
thank!
OMG so much easier to follow than crash course. Thanks You. This helped a Ton!!
+Alethea p ik crash course sucks he tries to make it funny and entertaining but its like dude i need the bare facts not a comedy lesson bc my grade is no joke
Mya Cook EXACTLY!!
Alethea p (:
@@myacook6388 I definitely agree
I don't think so.
Good luck on the AP test to those taking in 2018!
I am taking it 2019.
Taking it in two weeks but appreciate the luck anyways
Lol mine is tomorrow and i have forgotten everything i have learned in AP bio so far
im taking it tmr LOL
@@jeanniejiang3179 me too
It seems hard to find excellent biology lessons on YT without political or religious commentary. Thank you so much for such great lessons.
His videos are very good except for the religion comments. You didn't notice because you obviously believe in his religion- evolution. Why can't biologists stick to science and not interject their beliefs based on no scientific evidence.
Those aren't his comments, they're from other viewers injecting their perspective into the comments section.
Holy crap this dude is good. THANK YOU, I LOVE YOU
I had a panic attack when my ap bio test was within 2 days and I was still iffy on respiration and photosynthesis. These videos really help calm me down and serves as a great and productive review for my test. It really also helps clear up points made in the textbook and class lectures as well. Thank you for this resource!
I'm amazed at your ability to teach, as always.
Same here
Best explanation of this process I've found. Brilliant use of visuals too.
Your videos are perfectly put together. They are the definition of CONCISE, in a proper order, clearly and enthusiastically presented.... These things are easier said than done. thank you for your fantastic work!
You're simply incredible in making a subjects that are explained so difficutly in textbooks sound so much more down to earth.
Paul makes everything so simple & easy to understand quickly! In school, it seemed too
hard & complicated to catch on to. But now it all makes logical sense. But especially, he
seems to get people curious enough to want to learn more, which does take more mental energy & mind concentration. But it seems worth it to invest the time & energy to learn something useful like this! Like he says, these processes have been going on for millions of years. But people & animals would take it for granted, & not even stop & think how this life cycle goes. Our lives depend on this for our food supply. And some shade from trees, & beautiful flowers, & some medicinal herbs & spices! Also, a fresh source of fresh
oxygen for our clean breathing! Penny
thank you sooo much! my final exam is in 6 days and i could not figure out photosynthesis but the way you explained it made so much more sense
YOU ARE MY SAVIOR! After going to my college plant science class 4 times a week I found that I learned more about photosynthesis and cellular respiration from your shorter videos than any of those damn classes. I have my exam over this stuff tomorrow and for any reason I pass its thanks to you Bozeman!
Thank you, Mr. Andersen! I enjoyed the overall view about thylakoids and stroma. You also did a great job explaining the Calvin cycle and photorespiration.
Your videos are awesome--I love that you condense the material into the important topics. I'm getting ready to take my TEAS test and being able to listen to your videos throughout the day is really helping me get prepared.
It's really cool how he breaks it down, I didn't realize how similar photosynthesis was to the activation cycle of sight in animals/humans.
Your videos are great to study and I think I learned more about photosynthesis from you then my actual bio teacher.
Here I am, having watched your videos a year ago in high school biology class, now using them to study for my college exam tomorrow. Thank you Mr. Andersen. You have really helped me learn this material.
Found Mr.Andersen way too late but he still helped dramatically so i had to share him with some other classmates. God bless your soul mr.Andersen ( life saver )
Thank goodness I actually had you as my teacher last year! No way I would have passed if I hadn't! And it was still a hard subject, even with your videos on addition to you in class lessons....
Wowowowow this guy is awesome. Definitely getting me through m AP Bio course, and he cover in twelve minuted the exact same material my teacher struggles to teach and explain in an hour and a half.
Wow, crazy how well Paul can explain something, this hasn't stuck for months, after 1 video from Paul Andersen, I get it. Thank you!
I love how he always ends with "and I hope that's helpful" so unexpectedly in like the last 2 seconds of every video
Good luck to everyone on the 2019 AP Bio exam!😊
Caroline Clare I’ve found another wild 2019 AP Bio student, greetings comrade and good luck to you too
@@britterthecritter4531 I'm in college taking Molecular Biology, and this video teaches better than my professor.
Not AP I'm in the UK doing an a level exam in two days but I'm gonna take that luck anyway
thank u
@Jonah Shaya Honestly good luck with that
I love Mr. Andersen, he explains it very well and helps me a lot in my Biology class :)
wow, it's been 2 weeks that our teacher gives us readings to understand all the processes and I was having difficulty understanding. with your video, 12 min and I understood everything. thank you !!!!! great teaching skills!
Love this guy. i've been watching his videos since middle school and now I'm a junior in college and still rewatch these videos as refreshers. I know I'll continue watching his videos in grad school. He's one of the best.
who else is watching this because our biology teacher made us watch it
***** krizke boii
+Doge lazy ass teachers dont like to do their own damn job
+Doge I dont think they get paid enough. My teacher just goes on hapara and watches us so u know, not getting away with anything
ugh me
+Doge ME
THANKS FOR COMING TO SAS
+Sanya Lokur My pleasure. Great school.
Bozeman Science ⚫️tanks
This is helping me so much in my Honors Biology class. Not only is his voice soothing, but he does a great job at explaining the process of the Calvin cycle. Thank you :)
I'd been struggling with understanding photosynthesis for a while now, spending many hours just reading textbooks. thank you for explaining so well, you really helped me.
Who else is cramming for Monday? Hahaha
I am
Miguel M ME!!!
Miguel M me tooooo
Yassss
Miguel M bruh it's even worse when your teacher did absolutely nothing to prepare you for the exam DX
Mr. Anderson, you are a wonderful human being. Why are my teachers such drones? Is that what happens when you spend too much time in a lab and you adopt the communication skills of an automated phone operator?
This chapter makes so much sense now. Thanks for your help!
sir you have opened my eyes. my professor has explained this process to me for days, and i had yet to understand it until now. THANK YOU.
Biology test tmr- THANK YOU I LOVE YOU THIS WAS PERFECTTTTTTTTT!!!!!!!!!!
I can see clearly now the rain is gonneeee!
You're awesome man! I'm EXTREMELY appreciative of your hard work. Thank you!
Thanks so much for all the really helpful videos Mr. Andersen.
THANK YOU!!! Much more organised and sensible than Crash Course!! Also you explained it very well 👍😃
Your videos are really helpful. Thank you very much!
you're so good at explaining the concepts properly. thank you so much for this!
I had to watch this about three times in order to understand the whole concept of photosystem. Definately the best video watch!!! Thank you
Good luck on the AP test to those taking it in 2020!
shouout to anybody who is watching this to prepare themselves for the 2020 ap exams. haha
You are the man! Great explaining, more helpful than any other video I've seen online.
I am soooo grateful Paul Anderson exists. He somehow simplified this entire process and I actually find it interesting now- did not see that coming.
Helped me ace my ap bio test. Thank you sir
This video is amazing! Thank you for taking time to talk about it in depth! I am a visual learner, so the images (along with your detailed explanation) was very helpful! I took 5 PAGES of notes from this (I learn from writing things down)! Thank you, thank you!
Suddenly I happened to listen Bozeman’s lectures.It’s a great experience to me , as I from humanities background, very shortly I understood all the major concepts which raise many doubts in mind for four years. Now I am lessthan a science graduate comparatively. I must thank the wonderful scholar who might born with god’s bliss ! Whose lack me and the world living with me would have lost a lot and lot ! Thanks science world.
How genius is that CAM process in plants! 😱🤯
omg his laugh is so cute at 3:30. this was a life saver!
thank u for being the reason i pass ap bio
You're the best! I've been struggling to understand this process for several days now. Thanks to you, I think I've finally got it. Thank you so much :)
Omg, this was one of the pleasant and most comprehensive video I have seen.
So basically the light dependent reactions are part of the PSll and PSl and the light independent reactions is the Calvin Cycle?
yeah. That's pretty much how it's explained.
YES
Watching this the night before the 2020 AP Bio exam!
Thank you Paul..I'm studying for my advanced level examination and I'm from Sri Lanka..Video about photosynthesis helped me a lot for my studies.Anyway now I'm always referring Bozeman Science videos for my lessons .My exams are on 2022 August and now it's 2020..Anyway I'm always watching your videos, so that I won't forget those facts
Thank you. Thank you. Thank you. In the midst of a biology class with zero background in biology of any sort. This is so helpful.
plants are friends, not FOOD
take that vegetarians
You need new friends!
There both
Very detailed,good information,but a little deep for my MS students.
Hater
She wasn't hating, she was complimenting him. She was just saying that her students wouldn't follow it very well.
Use crash course instead- It's much more broad and consumable.
I'm doing CFE higher biology and it seems to at the right level for me, which isn't that advanced.
CC is good, but it has a lot of off topic analogies.
I thought I was done watching Mr. Andersen videos once I graduated high school.
And now my college ecology class is having me watch this. I can never escape.
One of the best explanations of simple concepts!
Although I do love him, I cannot comprehend why, as a High school student, I need to know any of this.
So is that why corn explodes, it's a C4 plant!
I've been trying to find a satisfactory explanation and every single video I've watched until now only made me more confused until this one. Really big help
after watching 5 videos, I finally fully understood the process in this video, thx with my whole heart!
2:48 Are plants just nice? No!! haha his laugh is so cute!
Photosynthesis is the process by which carbon doixide and water is transformed into glucose through the use of sun energy. The end result is oxygen being given off as a waste product.
Excellent clear explanation. Thanks! It's so easy to get totally bogged down in the detail of photosynthesis, (even some text books just jump right in there and tell you to go read a review paper) this was a really helpful overview
I finally get the exact process of photosynthesis now. Thank you so much for making this video
Mr andersen is so cute. I love nervous guys. He is so cute and nerdy. 😊
Why does the plant even need to respire or even have the calvin cycle ? since after the light reaction it produces ATP and NADPH . and that's what it needs . Pleasee answer this.. :) Thanks
It needs to store energy; so it undergoes the clavin cycle to produce glucose. So later it can break that glucose, in order to get ATP later.
ahan! thanks
plants make energy by photosynthesis or light reaction as you say. However, they need to live in order to do so, they also have to breathe just like any other organism, so they respire and use that ATP created in photosynthesis. Respiration just includes all regular activities - growing for example, fruiting, flowering all expends energy
Way easier to understand than my professor. Thank you. You are amazing.
Praise God! Excellent video to accompany my textbook. Mr. Anderson you really breakdown photosynthesis into bite size, digestible pieces. Be well and thank you!
who's watching this the day before the ap test??
how was test
me lol
Teachers: Study this NOW! Your test is in 3 weeks, you can't learn it in one day!
Mr. Anderson: *makes video teaching everything you need to learn in one day
Me: *aces test and proves teacher wrong, once again
Thank you very much mister Andersen. English is my second language. And sometimes it is very hard for me to understand the chapters of the biology book. I am so glad I can watch your videos before I read book. You are explaining it so simple. I wish I can have you on my lectures. Thank you for all that you did :)
this is just the best biology video ever.. so perfect and to the point, thank you Bozeman!
