Cellular respiration is a series of complicated reactions. some of the enzymes that are necessary for the reactions to take place effectively are not produced by the body and must be eaten in a person’s diet. which answer correctly explains what happens when a person's diet lacks the necessary enzymes for cellular respiration?
a. the production of atp will increase as the enzyme decreases.
b. the cellular respiration reactions will use another available enzyme.
c. the cellular respiration reaction rate that uses the missing enzyme will increase.
d. the cell's energy level will diminish as the enzyme decreases.

D. The cell's energy level will diminish as the enzyme decreases.

Explanation:

Cellular respiration in our body occurs so that our body could generate energy in the form of ATP primarily from carbohydrates. A series of reactions catalyzed by various enzymes facilitate cellular respiration. If our diet lacks the enzymes which are responsible for carrying out cellular respiration and there is no means to produce those enzymes effectively in our body then the cellular respiration reaction will become slow as less enzymes will be available to catalyze the reactions which lead to cellular respiration. Less enzyme means less conversion of substrates into products which leads to less production of ATP. If less ATP will be available then cell's energy level be low.
