Energy coupling occurs when
A)an endergonic reaction drives an exergonic reaction.
B)an exergonic reaction drives an endergonic reaction.
C)heat is generated.
D)allosteric interactions are at work.
E)chemical equilibrium is reached.

Question

Quizplus · Accepted Answer

Energy coupling occurs when an exergonic reaction, which releases energy, drives an endergonic reaction, which requires energy input. This allows the overall chemical reaction to proceed.

Therefore, option B is correct as it represents an exergonic reaction driving an endergonic reaction.
