Question

What is a specific region of an enzyme where a substrate binds and the chemical reaction occurs

Answer 1

The correct answer is an active site.  

The active site, in biology, refers to the region of an enzyme where the molecules of substrate combine and goes through a chemical reaction. The active site comprises of the residues, which produce temporary bonds with the binding site (substrate) and residues that catalyze a reaction of that substrate, that is, the catalytic site.  

Answer 2

Answer:

Active site is a specific region of an enzyme where a substrate binds and the chemical reaction occurs.

Explanation:

The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.

It consists of two sites:

• Binding site:

It consists of residues that form temporary bonds with the substrate.

• Catalytic site:

It consists of residues that catalyze a reaction of that substrate.
