Question

If the reaction in this graph is coupled with D  E, then D 
E is

Quizplus · Accepted Answer

Coupling reactions involve combining two or more reactions together to drive a non-spontaneous reaction using the energy released from a spontaneous reaction. In this case, reaction D 11eaa8b6_a15f_1a4e_a3f5_4923b3b617ef_TB4749_00 E is a spontaneous, exergonic reaction that releases energy. Coupling this reaction with reaction D 11eaa8b6_a15f_1a4f_a3f5_b50492dd9940_TB4749_00 E, which is non-spontaneous, endergonic reaction that requires energy, can drive the latter reaction forward. Therefore, the overall reaction is endergonic. Thus, the correct answer is B.
