A)consumes energy.
B)is not spontaneous.
C)is an endergonic reaction.
D)requires that energy is being transferred from phosphoenolpyruvate to ADP.
E)requires that energy is being transferred from ADP to phosphoenolpyruvatE.

Question

Quizplus · Accepted Answer

The reaction is exergonic (releases energy) as indicated by the negative Gibbs free energy change (-7.5 kcal/mole), meaning it is spontaneous and energy is transferred from phosphoenolpyruvate to ADP to form ATP.

The Reaction Phosphoenolpyruvate + ADP →\rarr→ Pyruvate + ATP Δ\DeltaΔ G = -75 Kcal/mole), A)consumes Energy

The Reaction Phosphoenolpyruvate + ADP $\rarr$ Pyruvate + ATP $\Delta$ G = -75 Kcal/mole),
