Coupled reactions are defined as
A)reactions that are linked together via the same enzyme.
B)reactions that are linked together,with the liberation of free energy in one reaction being used to drive the second reaction.
C)reactions that are not directly linked together but are require the same enzyme.
D)reactions that are linked together because they act upon common substrates.

Question

Quizplus · Accepted Answer

Coupled reactions involve two or more reactions that are linked together with the energy released from one reaction being used to drive the other reaction. This is often seen in metabolic pathways, where the energy from the breakdown of one molecule is used to drive the synthesis of another molecule. The reactions may not necessarily use the same enzyme or act upon the same substrate, but they are energetically linked in such a way that the energy released in one reaction is used to drive the other reaction.
