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.

    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!

    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.

    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 ...

    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 !
