Answer:
option E the coupling of an exergonic reaction to an endergonic reaction
Explanation:
ATP production is an example of energy coupling where energy that is derived from one system is used to drive the reaction of a second system. energy released by ATP hydrolysis (an exergonic reaction) is usually used to drive cellular functions; coupling with endergonic reactions (reactions that absorbs heat from the environment). Sodium potassium pump uses this energy derived from ATP hydrolysis to pump sodium and potassium across the membrane.
