Enzymes that catalyze endergonic reactions are likely to bind
a. to atp.
b. to phosphate.
c. to each other.
d. to adp.

Enzymes that catalyze endergonic reactions are likely to bind to ATP.

Option A

Explanation:

Endergonic reactions are mostly exothermic reactions in which the products are in a higher energy state than that of the reactants, such reactions requires an extra supply of energy  Thereby the enzymes that catalyse the reaction bind to ATP for energy .

In body's metabolism these endergonic reactions are considered to be anabolic. The metabolic reactions of the body are divided into anabolic and catabolic reactions, that is the building up and breaking down reactions.
