Question

in the graph below, which of the following statements must be true? a the reaction is exergonic. b the reaction will proceed without the addition of energy. c the reaction is endergonic. d the input requires the input of a single atp molecule.

Explanation:

Exergonic reactions release energy and have products with lower free - energy than reactants. Endergonic reactions absorb energy and have products with higher free - energy than reactants. In the given graph, the free - energy of the products is higher than that of the reactants, which indicates an endergonic reaction. An endergonic reaction requires an input of energy to proceed and cannot proceed spontaneously without energy addition. There is no information in the graph about a single ATP molecule input.

Answer:

C. The reaction is endergonic.
