This is a description of the process of chemiosmosis, which occurs in the light independent reactions of Photosynthesis. This video shows how the photosystems capture light from the sun and use it to power the chemiosmotic reactions within the thylakoids. It also shows how the ATP synthase is powered by the proton gradient. Be sure to check out the other videos in the playlist for extra review!

Glad it was helpful!
saving lives 6 and a half years later.... i love you
really thanks. I am preparing for an entrance exam and after seeing the confusing pages in books, this video is far far better.. Saved my time...
Did you clear the test, ?:
@@HayDayEveryday hey yes☺️ I am doing my medical studies in India
@@jenosigamani6904 omg amazing !! Did you do NEET? Are you doing private MBBS ?
@@HayDayEveryday yes cracked neet. Doing mbbs in christian medical college vellore
@@jenosigamani6904 Tips plz :o 🖐️
This is just amazing !!
I've tried many famous channel videos but still couldn't get it and was damn confused.
luckly I found this video and understood in one take ! yippe👯👯
You bought my subscribe !
Thanks for stopping by! Glad you liked it and found it helpful! I made these videos for my students and it always makes me happy when other people find them useful!
honestly so true
This is really helpful!!!!
So easy to understand and to catch up.
Thank you so much:)))
this really makes it easier to understand, thank you!
Thanks, but the new one is better! ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html It's less messy and you can't hear my students squealing in the background! Love, BOGO
I appreciate your efforts, explaining ground state and second singlet state!
Glad it was helpful! Sending love and (masked!) best wishes from Boston! -BOGO
Such a complex topic explained with such simple and lucid language. Thanks alot !!
Thanks a lot! I think this is the best explaination I have watch! ✋❤️
very creative diagram...i am a teacher so I know and I appreciate...nyc good luck
Thanks, Ullas! Let me know if there are other topics you'd like to see in videos. Good luck to you as well!
Now, it's easy to understand. Thanks for the video!
Thank you so much, you really cleared it up in a matter of minutes
THANK YOU, THIS IS SO HELPFUL
Very nice explanation
Thank you so much, this was very helpful🙏
Wow what a great lecture... Fantastic ❤️
great videos! botany student here and this was perfect
Thanks, JD!
Simply amazing
thanks a lot!! its was really helpful
Glad to hear it! Stop by any time!
Thanks for the video!🙏🏻
Thanks for stopping by!
Wonderful explanation ♥
Thanks, Ermina! Definitely check out the new version, ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html it's much easier to understand! Sending love and best wishes from Boston! -BOGO
thank you sooo much. it is very helpful...
Don't know y u have so less subs u clearly are good at explaining
Haha, well, I don't buy views and I don't buy advertisements! If I did I'd probably have more subscribers, and I should probably upload more often, but I just don't have time! I'd rather make a few good videos a year than make tons of bad ones.
Also, I made a better version of this video which is more detailed and has much better graphics. It's linked here. ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html

I thought that the photo excited electro on PSI once it passes through the electron chain and it goes back to the low level of energy then it will combine with the NADP+ to form NADPH. But in ur video u mention that the 2 electrons come the H2O that was split.. so my question is what happen to the electron after it goes down the electron chain? Help plz!
the best explanation.
Thanks, Anjii! I'm hoping to find time to make an updated (and much neater!) version soon!
YOU'RE SO SMART THANKSSSSS
Really useful thanks.
This is the easiest video ever on this topic....thanks a lot
You're so welcome, Farhan! Definitely check out the updated version of this video! ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html
So the electron moves through the electron transport chain, and at the end it is a low energy electron. Then photolysis provides the next needed electrons. But what happened to the low energy electrons at the end of the chain?? Does it get absorbed by the oxygen from the H2O or something before the O2 is released??
Awesome hats of for your explanation👍
Glad you liked it, Taha! I actually made an updated version a year ago (this original version was made with me literally sitting in a lab supplies closet in between my classes because it was the only semi-quiet space!) ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html Love, BOGO
I LOVED the video. idk how it doesnt have 20K likes. it'll now be my life's mission to get it to 1K or something
Ha! Thanks darcy! This is actually the old version of the video; literally made it in a closet in between classes back in winter of 2014 or 2015. There's a new photosynthesis video linked in the description. Sending love and best wishes from Boston! -BOGO
Best explanation
Thank you! Sending best wishes from Boston! -Bogo
Awesome 🙌
Thanks! The new version is much better! Much more carefully done, and more comprehensive! ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html
Great explanation 😍😍😍😍😍😍
Thank you very much .......
You are welcome 😊
OMG I very rarely leave comments but I just had to. You are the BEST! Honestly! I have been struggling so much to grasp the concepts of photosynthesis (since September)! I couldnt understand my teacher's explanations and though I did watch so many other youtube videos and read so many textbooks, for some reason everything just looked so confused! I don't know how but your explanation is just clear and concise! Just everything I needed! I absolutely LOVE your diagram! It just shows how everything "fits together" so well! You might have just saved my life hehe! Thank you SO MUCH!!! Just subscribed and am looking forward to watch your other videos because something is telling me that you're gonna make me ace my exams! :DD
Thanks, Bea! Photosynthesis and respiration are definitely pretty dense. Stop by any time!
really helpful !! thnku ☺
Glad you found it helpful!
THANK YOU SO MUCH
You're welcome, Ware! Sending you love and best wishes from Boston! -BOGO
Miss i still have 1 question. Does electron and proton are already formed in the stroma before photolysis happened.
THANK U SOO MUCH SAVIOURRRRRR
PLEASE CAN U TELL ME THAT WHERE DID THAT ELECTRON CAME FROM
I LOVED UR VIDEO
PLZ ANS THIS
Very helpful thank you
Thanks, Stroh! This is actually a pretty old video; I made an updated (better!) version which is linked here ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html
Take care! -BOGO
Nice video and nice illustration but i have few questions
1) What is NADPH and its abbreviation?
2) In the last part you mention that protons move through ATP synthase to travel from thylakoid to stroma due to proton gradient but from where that ADP and inorganic phosphates come from and react to form ATP and then what is the purpose of protons entering into the stroma in the formation of ATP?
Welcome, Muhammad! Good questions.
1) NADPH stands for "nicotinamide adenine dinucleotide phosphate" (you can see why I prefer its abbreviation!)
2) The ATP synthase complex is complicated and consists of multiple components all working together. The gradient turns it like a windmill and that energy is used to put together ATP molecules. The details were outside the scope of the high school class I was teaching when I made this video, so I didn't go into a lot of specifics. Take a look at this video (not my work but it's an awesome animation). It shows how we use the gradient to power the ATP synthase "machine" ua-cam.com/video/3y1dO4nNaKY/v-deo.html . It uses respiration as the example, but it should give you an idea of how it works
3) PGAL: Is half a glucose molecule. Photosynthesis churns them out and a pair of them forms Glucose.
Take care!
The video gave me good concepts but I have few questions which are confusing me.First one is ETC after PSsecond cytochrome complex makes ATP by chemiosmosis according to my book and second one is how H2O molecule can gives 3electrons?
Water splits to form only 2 electrons, I noticed that mistake too. But I think the low energy e at the end of PS 1is the third electron. Hope this helps!
Amazing tq mam..
You're welcome!
Wow. Absolute respect on this one. My Professor took 20 Slides to explain this and i didn’t get shit.
Thanks, night! Glad you found it helpful. I actually made a better version more recently (I cooked up this version in about 20 mins between classes...) The updated version is linked here. ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html Sending (masked!) love and best wishes from Boston! -BOGO
How comes there's no missing electron is PS1 because it goes through the same process as PS2 right?
Hi Edward. Good thinking! This is actually a pretty complex process and is enmeshed with the photolysis of water. When water molecules get broken down, one of the components is several electrons. These electrons feed into the photosystems to maintain the supply of electrons. They also (eventually) combine with NADP+ and H+ to make the important NADPH molecule that is used later. Have a nice day and hope this helps!
I see thanks for reply
Gr8 at last found it
Glad you found it helpful, Areeb! Come back any time
Thankew
You're very welcome! Definitely check out this new version of the video: ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html It's tidier and easier to understand! -BOGO
Thanks
You're welcome! This video is the updated version ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html
Happy studying!
4:34 i think you meant thylakoid membrane?
tysm
Where is the concept of accepter molecule when electron is released from ps 2
Hi Vijay, I actually made an entire updated video covering this topic and others, which is here. ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html
I made this older video in between classes, and was rushing, so it wasn't as detailed as I would've liked! (It's also why you can hear my students squealing in the background if you listen carefully!) It was definitely time for an upgrade!
-BOGO
What happened at 9:38..?
I made this back when I was teaching. Someone probably knocked on my office door, requiring me to pause the recording!
I hate to be critical, but your models are a little incorrect. There should be only two p680/p700 molecule or chlorophyll a. It is in the reaction center complex, and when all the pigment molecules get triggered it gets triggered. Other than that I thought it was a good video.
It's not being critical at all! You're totally right; careless mistake. I would much rather have someone point it out so I can stick a little annotation over it. I keep meaning to redo this video to show things more clearly, but haven't had time!
Who else drew this?
I draw everything myself, this is a really old video though, back before I was using a stylus. I made a new photosynthesis video, which is here. ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html Happy studying!
