Biomolecules Question 65

Question: Allosteric enzymes have allosteric sites for:

Options:

A) Inhibition only

B) Activation only

C) Reduction in activation energy

D) Both activation and inhibition

Show Answer

Answer:

Correct Answer: D

Solution:

The allosteric site of an enzyme is where a molecule that is not a substrate may bind to either enhance or reduce the enzyme activity.

Binding of an allosteric regulator changes the shape of the enzyme and influencing its overall activity

So, the correct answer is ‘Both activation and inhibition’
