- 048 - Enzymes
Paul Andersen explains how enzymes are used to break down substrates. The correct shape of the active site allows a key/lock fit between the enzyme and the substrate. The enzyme catalase is used to break down hydrogen peroxide. The importance of cofactors and coenzymes is emphasized. Competitive and allosteric inhibition is also included.

“I hope that’s helpful”. Sir, you are saving me, my grade, and my AP exam score, so YES, you are being very helpful, thank you so much.
you dont understand how relatable that is for me
this guy has single handedly saved my life
Are you alive? Where are you now?
One handed
Hmmm 22 pages to highlight for tomorrow's exam OR an 11 minute video explaining absolutely everything...tough choice.
redroses3010 22 pages to highlight for tomorrow's exam of course, how can you give that up man?
Yeah I had to ponder it really hard...I brewed to the point of sleeping.
+redroses3010 wtf! 22 pigs just about enzymes. wow, they must be giving the definition for every single word
Live Every Moment That's pretty much it and then ask very unrelated questions in exams! XD
redroses3010 lol
I just wanted to let you know how much your podcasts have helped me. I am a 33 year old stay at home wife and mother of 3, who has been out of school for a while ;). It was intimidating to go back to school, but you have made it a very positive experience, because I can relate to the way you teach! You make sense of every topic we are covering in Biology 12...so I thank you :).

Dinct and here you are again a year later lol
cool, but who asked for ur life story Becky?
you'll regret saying your age
Thanks, my AP teacher is completely incoherent.
same
My prof is completely incoherent. He talks for 3 hours straight then shows us these videos which explain everything better than he has in about 10 minutes. It's a waste of time.
My AP teacher literally assigned this video. ._.
Relatable
3:43 “let me stop talking about what I’m going to talk about and actually talk about it”😂😂🐐🐐
must...cram...
eh
Katherine Pierce he didn't disrespect
bro, you are awesome.
Juniorall thanks bro
+GAMAL MOSSALEM your stupid what?
+GAMAL MOSSALEM You're* who's the stupid one now? :3
+GAMAL MOSSALEM at least make sure you can say an entire sentence correctly before calling someone stupid.
God bless you! My terrible horrible AP biology teacher makes me want to cry every day and biology is my favorite subject! All of your videos have helped me so much, I can't thank you enough. I'm so glad there are generous and dedicated people like you out there who take their time to share these things.
I'm from jamaica and this really helped me to pass human and social biology , thank you

Sir, you're videos are the best! You're able to teach me something a lecturer cannot teach me in a 1 hour lecture in 10 minutes! :D thank you!
I would like to say that I love watching your pod casts. You have helped me understand the my learning material in my college courses: Biology, Genetic, and Microbiology. I greatly appreciate having someone that can re-explain what my teachers are trying to teach us.
Thanks dude you are saving my bio grade! - Malachai Tea
3 minutes of your video, and it makes more sense than a 30 minutes lecture in class! Thank you!
fax
Anytime I get stuck with something when I'm studying I know I can rely on your videos. Thank you for the effort and creativity!
I have never been more grateful for anything in my entire life! Thank you!
HOLY CRAP!! I have a freaking week to know everything about bio. You sir, are a life saver!!!!
bro i have tonight...

@@linusbao8650 how did ur test go
@@lisabella221 uhh, I dont remember lol. Probably well, I got an A in the class.
You are great at explaining everything clearly and in just few minutes
That is super cool... honestly this made my mind blow away. Such complexity and sophistication in these tiny, miniscule thingamajigs.
excellent video. however the "lock and key" model at 4:11 has since been changed to the "induced fit model" because the enzyme is not exactly the right shape to fit in and so needs to be "induced"
Nah it hasn't change, those are just theories as some Biologist said that the enzyme and substrate both have complementary shape so forming a perfect fit(Lock and Key hypothesis) BUT other biologist said that the enzyme change its active site shape and then the substrate fit on it(Induced fit hypothesis)!!! these are just assumption about how they work and they haven't been really prove about exactly how they work so learn both of them!!! Enzyme is very easy!!!!
Man your videos are the greatest biology lessons on the web ! I've got a biology teacher which isn't as good ... if you see what I mean ..
Your videos are a great and pleasant way to understand biology easily and with amusement !
I often put these types of YT-videos on higher speed, but this I considered slowing down a little bit. This is my compliment to you. Well presented.
You are the best teacher ever! Thank you very much for that what you're doing! You are helping me a lot!
Your videos are amazing.
softypapa you're
haha, no
haha
Bozeman you are incredible, I would be so lost without your videos. You are my hero
I have semester finals tomorrow and this guy is a lifesaver
Allosteric inhibition that actually changes the shape of the active site has always been my favorite because it is magical :)
This is by far the best explanation that I have received. All his videos are amazing. Thank you
Bozeman Science This is PERFECT. Amazing. Wow. In class I had to do this, never got it, until now! Thank you so much.
Great video on enzymes. I wish I had found your series at the beginning of the semester! You make it so easy to understand without completely "dumbing it down". Thanks!
thank you for this clear but detailed explination, you sir are doing the lords work
Not only is this super helpful but you literally have to most satisfying voice I have ever heard.
Thank you. Please don't stop posting videos like this. Helps a lot
Mr Andersen, how do I thank you for saving me in Biology?
Go out and be awesome. Help others and make the world glad you are here.
+KnowJesusKnowPease lol gay. Just say thanks?
Joe Palmer lmao true
All of your videos are so helpful. Thank you for taking the time to put them together. They have helped me in almost of my clinical chemistry chapters.
thanks for spreading knowldege in such a graceful manner! when i was in highschool my teachers suck and i lost my interest in learning.
The cofactor is a non-protein that bonds with the protein to complete the active site or 'activate' the enzyme. Now cofactors can be divided into two groups, which are prosthetic groups and coenzymes. A prosthetic group is a chemical that strongly bonds with the protein in which it becomes permanently bonded with the protein (such as heam). While on the other hand co-enzymes (usually oranic, non-protein) are weakly bonded to the protein which means they tend to break off once the reaction occurs
You're explanations are f*cking incredible
Language!
@@fancy4458 and spelling too (*your). Damn I was in school when I first commented. I'm now in my last year of engineering. Never would have thought this would happen.
F*cking study enzymes kids! Specially if u have this sort of teaching for free!
@@franciscobastida7845 That's crazy. Do you even remember commenting that 6 years ago?!
@@franciscobastida7845Hey!! Whats up??
Thank you for all these chem videos, they've helped so much.
Oh my gosh this helped so so much. Thank you for putting the time into this!
omg thank you so much, I had such a hard time understanding competitive vs noncompetitive inhibition from my book!
Absolutely well explained. Thank you very much.
Thank you! I have been stressed about bio but you make it easy to understand! So grateful for these videos
Your videos are helping me so much to study for the TEAS exam. I wish I would have found your videos when I was taking the actual classes!!!!! Thank you so much!
Excellent as always, Mr Andersen!
You are the Best..Helping me get through Nursing school..Not so in depth sometimes but great videos..You have helped me alot...Go Mr.Anderson
"let me stop talking about what im gonna talk about and actually talk about it" looooool
Joel Ferrel god, i read this right when he said that
Awesome video! Thanks for taking your time to explain it so well.
My god I love you. Please don't stop uploading! My future literally lies between your hands right now.
Thank you for your videos! They are so helpful as they are helping me through my forensic chemistry degree! 4 exams that I was worried about until I saw your videos! Thanks again
Thank you for this video! I am looking forward to more topics posted. This video is very helpful and easy to understand.
Thank you for not being boring.
Thank you so much. I first found enzymes a very difficult topic but after watching your video I think it is very interesting.
Thank you for your help Mr. Anderson, love how you say "I hope that was helpful" all the time :D Wish my lecturers were as helpful as you!
Your videos have helped me so much. You have taught me more in an hour than most teachers have taught me in my lifetime. After seeing your videos I understand and I now like Biology. :) So thanks, from me and my study group!
Such an interesting video. Thank you so much for it. :) It helps me a lot, especially in overcoming the boredom of studying using the books. Appreciate.
Thank u so much for your vids. They really are more simplified and easier to understand than my bio teacher and homework combined. You're a lifesaver :)
Your videos are always awesome and simple. Thank you!
thank you very much for uploading these very informative and comprehensive videos
your videos are awesome, every single one of them.
Nicely illustrated Sir. I will recommend this video to people.
I cannot thank you enough for this sir :) ! You're truly the best at what you do! :)
Thanks man, very informative, elucidating lecture on enzymes. I really appreciate you for sharing.
I love your videos!! It makes so much more sense. Thank you a billion
this was super helpful :D it covered everything I needed
Thank you! My AP Bio teacher doesn't go into as much depth as you, which is awesome! Thanks so much
Another brilliant video, thank you.
Great video, I was directed to this video from johns hopkins course, and I was not disappointed!
He's a wizard! thanks for explaining clearly and efficiently :)
Been hoping for an enzyme video, thanks!
My Biological Sciences one teacher in college has put a link to pretty much all of your biology videos so these videos are also very good for teaching college students :).
It's very helpful. Thank you. After watching this video, I am sure I will do well on my assignment tomorrow.
Never stop uploading. Mostly because my understand of Biology and an A in my AP Bio class is now coming from you.
P.S. You rock!
actually i am very happy to watcth your enzyme allosteric regulation and it made me so comfortable to teach my students....... thank you sir...
Thank you, you make it look so easy!
Wow thank you so much! You're a much better teacher compared to the teacher at my school.
I love Mr Anderson . Thank you very much . You made many thing clear for me .
I love your way in explaining things .. thanks soooo much
very useful. Better than ten lectures in the university.
Your awesome ! Your videos have the best explanation. Its a hidden treasure of knowledge !Great Channel and Keep up the god work!
Thanks, really helpful, you're a great teacher!
Love these videos. Very helpful. Keep making them please.
Excellent piece of work
Always enjoy your videos, I am bad with chem and micro bio but your vids always help me to understand it a little better. Thank you.
man, you make waaaay more sense than my ap bio teacher. the drawings really help too
Thank you, these videos are helping me in my class.
Thank You! Keep making videos please, your awesome!
Awesome video, very descriptive!
You are amazing. You have saved my AS level biology.
this tutorial saved my life thank u
Phenomenal video. Where were you 20 years ago in my first chemistry class?? I this should be part of every chem classroom in the states. More kids would be inspire to learn chemistry "The Central Science". Thank you
Always great videos, keep uploading!
Thank you! Good summary of many aspects regarding enzymes.
Thank you for the helpful explanation. It is very much appreciated to any biology student.
All your videos are very helpful thnks for taking the time to putting them together
I wish my teacher was this informative, interesting and got straight to the point -___-
It's very helpful thank you!
Extremely helpful! Thank you!
excellent explanation, After this video, I did not have a problem teaching about enzymes. Thanks broo
