Question

In the lock-and-key model of enzyme action, the ___________ fits into the __________ of the enzyme.

A) product; substrate.
B) active site; product.
C) substrate; active site.
D) active site; substrate.

Answer 1

(c) substrate fits into the active site of the enzyme.

Answer 2

Option (A).

Step-by-step explanation:

Enzymes are bio catalyst that can increase the rate of a biochemical reactions. The enzymes work at specific pH and temperature conditions of the body.

The enzyme follows the lock and key model. According to this model, the substrate fits into the active site of the enzyme. The shape of substrate must be identical to the enzyme's active site.

Thus, the correct answer is option (C).
