Question:

Chemical equilibrium is relatively rare in living cells. Which of the following could be anexample of a reaction at chemical equilibrium in a cell?

A) a reaction in which the free energy at equilibrium is higher than the energy content at anypoint away from equilibrium

B) a chemical reaction in which the entropy change in the reaction is just balanced by anopposite entropy change in the cell's surroundings

C) an endergonic reaction in an active metabolic pathway where the energy for that reaction issupplied only by heat from the environment

D) a chemical reaction in which both the reactants and products are only used in a metabolicpathway that is completely inactive

E) There is no possibility of having chemical equilibrium in any living cell.

Answer:

D) a chemical reaction in which both the reactants and products are only used in a metabolicpathway that is completely inactive
