Match each function with the correct enzyme class.

1) transfer functional groups between molecules

2) catalyze intramolecular rearrangements

3) catalyze redox chemistry

4) catalyze the joining of two molecules together

A) oxidoreductases

B) transferases

C) hydrolases

D) lyases

E) isomerases

F) ligases

The correct matching pairs are:

1) - B)

2) - E)

3) - A)

4) - F)

Explanation:

Transferases (B) : Transeferases is the class of enzyme that catalyzes reactions involving the transfer of certain functional groups. (1)

Example: Transaminase transfers nitrogenous groups

Isomerases (E) : Isomerases is the class of enzyme that catalyzes isomerization reactions and intramolecular rearrangements. (2)

Example: Triosephosphate isomerase interconverts aldoses and ketoses

Oxidoreductases (A) : Oxidoreductases is a class of enzyme that catalyzes redox reactions (3) which involves the simultaneous transfer of electron.

Example: Alcohol oxidoreductases acts on the alcohol functional group

Ligases (F) : Ligases is a class of enzyme that catalyzes reactions involving chemical bond formation between two molecules. (4)

Example: DNA ligase joins DNA fragments
