Question

What are some examples of enzymes?

Answer 1

_________-
Enzymes are biomolecules which act as catalysts , they increase the rate of a reaction.
For example, enzymes play a key role in breaking down the food we ingest, here hydrolase enzymes play a role.

1) hydrolase enzymes : catalyse hydrolysis which is the breakage of single bonds by the addition of water.
The digestive enzymes are all very specific depending on the food they need to break down

• proteases / peptidases help break down protein in our food, they break the peptide bonds between amino acids which in turn helps breakdown proteins (amino acids are building blocks of protein)
• lipases break down lipids into fatty acids and glycerol by breaking the ester bonds

2) Transferases
catalyse the movement of one functional group from one molecule to another (it helps “ transfer ”)

3) Oxidoreductases :
catalyse (oxido ) oxidation - (reduct) reduction reactions, wherein electrons are transferred from one molecule (the reductant) to another molecule (the oxidant).
