The diagram represents an endergonic reaction. How is such a reaction driven forward in cells?
- A
Addition of an irreversible inhibitor
- B
Spontaneous occurrence at standard temperature and pressure
- C
Removal of all enzymes from the cytoplasm

Coupling with an exergonic reaction such as ATP hydrolysis
Explanation
Endergonic reactions (ΔG > 0) are nonspontaneous. Cells couple them to exergonic reactions, most commonly ATP hydrolysis, to make the overall ΔG negative.
