Quizplus · Accepted Answer

For two reactions to be coupled, one of the reactions must be spontaneous to drive the non-spontaneous reaction, and a product of one reaction must serve as a reactant in the second reaction. This allows the energy from the spontaneous reaction to be used to drive the non-spontaneous one, often seen in biochemical pathways.
