Question

Differentiate between exergonic and endergonic reactions.

Answer 1

All reactions occurring in the living system may be exergonic or endergonic Those reactions which result in the release of free energy. are classified as exergonic reactions. These are the reactions that tend to occur spontaneously. On the contrary, in endergonic reactions, free energy must come into the system from outside; In biological systems, endergonic reactions are only possible if they are coupled with exergonic reactions that supply the needed energy.
