Endergonic

adjective

BIOCHEMISTRY

(of a metabolic or chemical process) accompanied by or requiring the absorption of energy, the products being of greater free energy than the reactants.

[detritus-of-an-ap-bio-kid]

Endergonic reactions absorb energy from surrounding and excess energy making the free-energy change is positive (🔺G). They are non-spontaneous, anabolic reactions. Exergonic reactions release or lose energy, meaning the free-energy change is negative (-🔺G). ATP is what powers endergonic reactions, which occurs in photosynthesis. ATP removes a phosphate group from the membrane and attaches it to the reactant. This is called phosphorylation and forms ADP. The energy released from forming the ADP drives the exergonic reaction, starting cellular respiration.
