1. a(n) a molecule that can bind to an enzyme and prevent the enzyme from working. there are two types: a( binds to the active site of the enzyme; a(n) elsewhere on the enzyme.

Enzyme Inhibitor

Explanation:

"An enzyme inhibitor is a molecule that can bind to an enzyme and prevent the enzyme from working. There are two types: a competitive inhibitor binds to the active site of the enzyme; a noncompetitive inhibitor binds elsewhere on the enzyme."

Enzyme inhibitors also can separate in two categories:

- irreversible inhibitors : cannot be reversed

- reversible inhibitors:can be reversed (competitive, noncompetitive, and uncompetitive inhibitors).

An Enzyme Inhibitor, Competitive Inhibitors and Non competitive Inhibitors.

Explanation:

An Enzyme Inhibitor is a molecule which alters the catalytic action of an Enzyme.

The two major types of an Enzyme Inhibitor includes :

Competitive Inhibitor : they are known to bind to the active site of an enzyme.

Non -Competitive Inhibitor: are known to bind to another site on the enzyme.
