Option (1).

Explanation:

Enzymes may be defined as the bio catalyst that has the ability to increase the rate of a biochemical reaction occur in the living organism. The enzymes works at specific pH and temperature conditions only.

The enzymes are added to increase the rate of the reaction.Enzymes decreases the activation energy of the reaction by increasing the effective collision between the substrate.

Thus, the correct answer is option (1).

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
