Which of the following actions would increase enzymatic activity in a bacterial cell that normally thrives in the human body? a. slightly increasing the temperature within the optimum range b. increasing the substrate level in the environment beyond saturation c. adding a second substrate that can act as a competitive inhibitor d. placing the bacteria in the refrigerator

Option (1).

Explanation:

Enzymes is the biocatalyst that has the ability to increase the rate of a biochemical reaction of the living organism. Enzymes decrease the activation energy of the reaction.

The bacterial cell has the ability to thrive into the human body and may acts as pathogen. The enzymatic activity of the bacterial cell can be increased by increasing the temperature but the temperature should be in the optimum range of the enzyme.

Thus, the correct answer is option (1).
