Six types of enzymes | Chemical Processes | MCAT | Khan Academy
Enzymes are often named for their reactions, and you can often discern the function of an enzyme from its name. We will learn about six types of enzymes based on the type of reaction they catalyze. By Ross Firestone. Created by Ross Firestone.

Good job but (in my opinion) he should have numbered them according to the enzyme classification system to avoid any confusion. The first number in the enzyme classification number is one of these 6 classes. So 1 = oxido-reductase, 2 = transferase, 3 = hydrolase, 4 = lyase, 5 = isomerase, and 6 = ligase.

Thank you very much
If a reaction is breaking one thing into two you should use AB----> A + B instead of A----> B + C because that can be confusing and make people think that it is creating something new or different. Just a suggestion!
All your videos are interesting Sir, I can totally understand enzymes better now. Thank you!
Dude!! You've saved my life. Thank you
Welcome to my channel ❤️😍
thank you sooooo much you helped me with my biology project , I was confused and didn't understand what these types are doing , thank you again! have to go now to continue doing my project!
I am from Myanmar. What we are taught here is to learn the enzyme classification exactly matched with the order. You just state all 6 enzymes with the wrong order. Well, it's not your fault. I know it's our problem. What's more, to study them by heart is what stress us more. Please help our university. It is the only prestigious university of medicine in our country.
Would've been nice if you used the EC class order for the 6 groups in stead of scrambling them :)
BIG THANKS FROM THAILAND YOU JUST SAVED MY LIFE FROM MIDTERM
Great and really helpful material, thanks a lot!
This is so helpful. Thank you!
At centre core of some protein enzyme activity are metal element cofactors, like cobalt copper zinc selenium iodine....these are your trace elements, they help the enzyme do its job.
Thank you so much that is very helpful..
enzymes are in the wrong order of classification: 1. oxidoreductase 2. transferase 3. hydrolase 4. liases 5. isomerases 6. ligases this order is more specific and can be used when naming the enzymes

tRNA synthetase? The ones that bring tRNA to the mRNA, which categorry does tht fall under?

isn't Ligase the class of Enzymes that breaks Water,Carbon Dioxide and Ammonia molecules?
Lyases generate either a double bond or a ring
never knew there were 6 of them.
what about synthetase?
Great

Well, in that case, the body wouldn't 'work' properly. The enzymes would be no longer able to speed up reactions (metabolism etc) in the organism (atleast how it is supposed to be). And if reactions get slowed down, then we have a big problem when it comes to the 'function' of the body as a whole. For instance the transformation of glucose into ATP which will help the body get some energy... I might be wrong, but that's how I understood it ...

I don’t think that your explanation about lactate dehydrogenase is correct. Lactate dehydrogenase remove H from NADH and transfer it on Pyruvate ( reducing pyruvate to lactate ) and oxidizing NADH to NAD+ Carbonyl group in pyruvate become OH-C in lactate
@anandasaravanan6973

Please note that the reaction is reversible. So both the statements are correct.( Oxidation of lactate or reduction of pyruvate, depending on presence of which cofactor is predominantly present)
you are too fast . . .

There is a mistake here.. Enzymes do NOT lower the activation energy, they only create a shortcut from reactants to products with a lower activation energy. It is like when you use a tunnel to cross through a mountain, you dont actually lower the height of the mountain, you only use a shortcut. It is different !
@SuperAbdihakin

+Chau Tran Well, what you are saying is not quite right. An enzyme bonds with a substrate by weak bonds. The formation of these weak bonds releases free energy which can be used to overcome the factors that lead to the activation energy.
