Question: what are endergonic and exergonic reactions?
Answer: Endergonic and exergonic reactions Reactions that have a negative ∆G release free energy and are called exergonic reactions. (Handy mnemonic: EXergonic means energy is EXiting the system.) ... Reactions with a positive ∆G (∆G > 0), on the other hand, require an input of energy and are called endergonic reactions.
