The enzyme phosphoglycerate mutase operates at $\Delta$G ≈ 0 kJ/mol. That indicates that the reversibility of that reaction
A) is spontaneous.
B) occurs rapidly.
C) occurs at equilibrium.
D) is nonspontaneous.

Question

Quizplus · Accepted Answer

The fact that the free energy change (ΔG) is close to 0 kJ/mol indicates that the reaction is at equilibrium. This means that the forward and reverse reactions are occurring at the same rate, leading to no net change in the concentrations of the reactants and products. Therefore, choice C is the best answer.

The Enzyme Phosphoglycerate Mutase Operates At Δ\DeltaΔ G ≈ 0 KJ/mol
