Which of the Following is TRUE of an Endergonic Reaction

Question

Which of the following is TRUE of an endergonic reaction?
A) The only product of the reaction is water.
B) The reaction proceeds spontaneously.
C) The change in energy of the reaction is positive.
D) Endergonic reactions never occur.
E) The only product of the reaction is heat.

Accepted Answer

Endergonic reactions require an input of energy to proceed because the change in free energy ($\Delta G$) is positive. This means that the products of the reaction have more free energy than the reactants, indicating that energy is absorbed from the surroundings during the reaction.
