Question

Each enzyme has a temperature at which it works best. A slight increase in temperature can increase enzyme activity while a large increase in temperature can cause the enzyme to become denatured. Which of the following best explains what happens when a protein becomes denatured? ...?

The enzyme absorbs heat until the temperature decreases, and the reaction then continues normally.

The enzyme breaks apart into the amino acids that originally combined to form the enzyme.

The enzyme loses its shape and is no longer able to catalyze chemical reactions.

The enzyme unfolds and refolds into a different shape, and is used to catalyze a different chemical reaction.

Answer 1

Option (3).

Step-by-step explanation:

Enzymes are the bio catalyst that can increase the rate of a bio chemical reaction without themselves going under any change. Enzyme decreases the activation energy of the reaction and increases the rate of reaction.

Denaturation of protein results in the loss of biological activity of enzyme. The enzyme loses its shape and cannot catalyze the reactions as enzymes are shape specific.

Thus, the correct answer is option (3).

Answer 2

"The enzyme loses its shape and is no longer able to catalyze chemical reactions" is the one among the following choices given in the question that best explains what happens when a protein becomes denatured. The correct option among all the options that are given in the question is the third option.
