Energy Coupling Occurs When

Question

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.

Accepted Answer

Energy coupling involves the transfer of energy from an exergonic process to an endergonic process. This means that the energy released by the exergonic reaction is used to drive the endergonic reaction. Therefore, option B is the correct answer.
