Endergonic reactions require input of energy to proceed because they increase the system’s free energy (ΔG is positive). Since they raise the energy of the products relative to the reactants, they don’t occur on their own and must be driven by an energy source, often by coupling to ATP hydrolysis or other energy-releasing steps in the cell. This is why the true statement is that they require energy input to proceed. In contrast, reactions that release energy have negative ΔG and can proceed spontaneously (exergonic).
