- www.handwritten... - This tutorial is the third in the Cellular Respiration series. This tutorial provides an overview of the TCA Cycle (also known as the Krebs Cycle) with a particular focus on the carbon balance throughout the cycle and the enzymes involved in each step.

Amazing! I have a biology exam in a few hours and before watching this video I did not understand a single thing about Krebs Cycle.
Watched it twice and now I feel fully prepared.
Thankyou so much! :D
hahaha... I am you right now!

And I'm both of right now!
Zeba Fariha People should consider giving their money to this guy instead of to these bad teachers who didn't teach them a thing, then. They don't deserve the money, contrary to this guy. We should support great people, not bad people. Vote with your wallet.
Totally agree with you! I wish I could help him financially, we don't have paypal in our country and I don't have a visa card yet. However I am soon going to get one, and hopefully will be able to support him.
the broad marker is oddly satisfying...okayyy..back to studyinggggg
its arousing loool
Acetyl-CoA is not a two carbon molecule, but rather the acetyl functional group has two carbons. That's what the video meant, but I wanted to clarify!
You, sir, are an inspiration. Thank you for existing.
@christian honey All the PDFs are available on the website.
This is the best explanation by a long shot. Thank you!
I rarely comment on videos, but your effort is too good to be left unappreciated. Cheers!!
Can we expect the Electron Transport Chain video? Really love all of them.
Thank you so much this is really a big help, please continue making tutorials sir and may God bless you more.
I'm a student in Phillipine Normal University.. Thank you so much for this. It is really a great help in my report :)
Your videos are so helpful.
Please make one on light reactions and dark reactions of photosynthesis , too.
Please it's a request .
SO. FREAKING. AWESOME. And so easy to follow and understand!! Thank you so much!
that was an absolutely beautiful and clear explanation of the tca cycle--awesome work! thank you!
This is the best tutorial video I have ever seen.
Finally an explanation that makes sense. Thanks you so much. God bless you.
Now...how to memorize this overnight?...
***** good luck ;)
Faatimah B Notice that the enzymes are usually named after the molecule they produce or decompose, or a molecule they modify somehow. So knowing the molecules, you have half the work done. Just attach the names of the *functions* of these enzymes ("kinase" if it moves around the phosphates to/from ATP/GTP, "isomerase" or "mutase" if it modifies the molecule, "synthase" if it synthesizes a new molecule from two smaller molecules, "dehydrogenase" if it moves hydrogens by reducing NAD+ to NADH or FAD into FADH2, or simply add the "-ase" ending to the name of the molecule which is being decomposed).
Harder thing is to memorize the names of the molecules. But since they have similar endings, you can try making a poem or a song out of them, or use some associations (e.g. I use a picture of a lemon to represent citrate, a big "A" to represent the CoA coenzyme etc.), and I try to remember where do they fit in the picture of the cycle.
Bon Bon thanks a whole lot for your explanation! Yeah I guess your ideas will make everything much easier.
Bon Bon ur great really thank u alot easiar this way
***** Yes, but it only helps you to remember the order of these molecules, not their actual names. And it is the names that people find the most difficult to remember. In your mnemonic, you still need to know what these first letters stand for in the first place, so it has the same problem that most misused mnemonics have.
WOW very very helpful! This made more sense than anything else I have looked at. Thank you so much!
This made so much more sense thank you so much!!!
This is just what I needed thank you Y'all keep up the good work .
WOW! You made it so much easier, thank you!
great lecture Mate! Greetings form Sydney!
awesome!! now I can finally understand Krebs cycle thanks a lot 😊
great video, but you did not explain how GTP forms ATP by giving it's phosphate group to ADP
Thank you this was explained brilliantly! For anyone that missed the comment below by Ashley Hermes!:
Remember this
"Citrate Is Kreb's Starting Substrate For Making Oxaloacetate."
The first letter of each word in the above sentence corresponds to the first letter of each molecule as you progress through the cycle. (Cirtrate, Isocitrate, Ketoglutarate, Succinyl-CoA, Succinate, Fumerate, Malate, Oxaloacetate)
Thanks. I just have one question, Why can't citric acid be converted directly to isocitrate? Are there any enzymes that can coordinate that process?
this video is simple and amazing ! Easy to understand it :D thanks a lot
SuSubscribe to my channal
plz make video on inflammation
This is beautiful
you missed the oxalosuccinate after the isocitrate molecule?
This is so helpful! Thank you so much.
its really a big help!!! easy understanding nd learning a lot , thank u prof :)
Hi, thanks for the video.It gives a lovely review without the extra waffle.
With the link reaction, isn't the enzyme a pyruvate decarboxylase complex?
great explanation
this vedio really helped me alott...thnx
you drew such a perfect circle *_*
So hummmmm,,,,Question? Which Fruits and Vegetables would you have to eat to get the right enzymes to produce the ATP in the Creb Cycle ???
Tom Scott Good question. I'd like to know the answer too. Especially for the Coenzyme A, which seems to be key to metabolism of fatty acids (in other words, it doesn't let you become a fat ass :P ). My guess is that you need to eat stuff which contains some precursors to the CoA, such as pantothenic acid. Just take a look at the molecule and try to figure out its constituents. They will surely be needed in your diet to synthesize the CoA.
thank u very much . it's very helpful to me .....
this helped me alot! thankx!
Kindly help to draw a pain and its inhibition by pain killer....?
this is very helpful!!!! THANKYOU
Thank you!
I LOVED it 💕💕💕thanks
thank you! you are a big help!
Thank you this is really helpful 💜💜
thank you so much
Wow really helped me thank you
Very easy very helpful
this was amazinggg!
perfect. thank you
THANK YOU SO MUCH
finally I understand now!
GREAT VIDEO! VERY NICE HANDWRITING AND DRAWING. LOL
Thanks 👍
thanks
Hats Off !
Wow thanks!!
God bless youuuuuuuuu💗💗💗
Nice one
Dude You Rock!!! thanks!!!
I heard at 1m45s that you said "Acetyl CoA is a two-carbon molecules". Is it right? Because I search on Wikipedia, and they say Acetyl CoA is a big molecule? en.wikipedia.org/wiki/Acetyl-CoA .
I'm not a native English speaker. So sorry.
Acetyl CoA =acetyl group"which has two carbon atoms" + co-enzyme A"which is a co-enzyme derived from pantothenic acid and has a complicated structure " ......so CoA is just a carrier for acetyl group and doesn't actually enter the cycle and what is meant by the two carbon molecule is the Acetyl (2C) that combine with oxaloacetate (4C) to form citrate(6C)
I want to say thank you very much. Now I got the idea :)
thanks sir
Very helpful
Thanks a lot :)
it help me a lot. thanks
Thank you 👌🏻✨
super sir
thax
can you want to collaborate?
valiuable........!!!!
10 ATP per cycle right?!
NICE
These might just save my ass for my uni exam tomorrow!!
Loveeeeeee ittt ❤❤❤
Muy bueno, gracias :)
fuking beautiful
i lost it once he said oxaloacate
Kelsey Mo same lol...
how comes?
And tomorrow, my IB externals......
it's not playing 😑
saved my time 😈😈😈
damn, it was sooooo f**king easy.
perfecttttttttttttttttttttt
Donate!!
fuck !!! why cant I watch it ?
aint no one gonna donate to you
Yeah thats right 3NADH = 7.5ATP, 1FADH=1.5ATP, 1GTP=1ATP, therefore 10ATP in total.
thanks.
i can give nice comment thanks love ur videos
you're australian am i right?
thanks prof
you are a big help!
What about Pyruvate carboxylase?
In Marks Medical Biochemistry, it says 12 ATP, because 1 NADH would be oxidized to make 3 ATP, 1 FADH2 to 2 ATP and 1 GTP to 1 ATP, overall 9 + 2 + 1 = 12 ATP. Do you know whats right?
Isn’t this too complicated for A level bio? Just wanna know
this is the only krebs cycle vid that worked for me. thank you!
I'd like to buy you a drink man! You are such a big help....=)
awesome if only professors knew how to teach it this way....
your drawing is aesthetically pleasing. good job with the TCA cycle. clear and simple and fairly short
Great!!! Keep them coming :) UREA CYCLE pleeaseeeee :)
A cycle = A turn, or 2 turn to complete the cycle ?
thank a lot..your video help me to understand it well
thank u very much. it was greatly useful.
thnk u so much ur vedio gonna help my exams thnks
