Exergonic
| Formula / Notation | ΔG < 0; spontaneous; ΔG = ΔH − TΔS < 0 |

| Also Known As | Spontaneous reaction (ΔG < 0), exergonic process, free energy releasing reaction |
What is Exergonic?
A process or reaction that releases free energy (negative ΔG). Exergonic reactions are thermodynamically spontaneous and can do work on the surroundings. Cellular respiration is an exergonic process that releases energy stored in glucose.

A process or reaction that releases free energy (negative ΔG). Exergonic reactions are thermodynamically spontaneous and can do work on the surroundings. Cellular respiration is an exergonic process that releases energy stored in glucose.
Exergonic coupling is the fundamental mechanism driving biosynthesis: ATP hydrolysis powers muscle contraction, active transport, and synthetic reactions that are endergonic on their own. Understanding exergonic vs. endergonic reactions underpins biochemical energetics and metabolism.
Highly exergonic reactions (especially those that are also strongly exothermic) can release energy rapidly and cause runaway conditions. The thermodynamic spontaneity (negative ΔG) indicates a reaction will eventually proceed but gives no information about rate — kinetic barriers may slow it to safe…
