A free-energy diagram for a hypothetical biochemical reaction is shown.
The diagram represents which kind of reaction?
- A
Isothermic - no change in free energy
- B
Endergonic - requires a net input of energy
- Ccheck_circle
Exergonic - products have less free energy than reactants
- D
Equilibrium - no net direction
Explanation
The products lie below reactants on the free-energy axis, so ΔG is negative. The reaction releases free energy and is exergonic (spontaneous).
