During endergonic reactions, reactants with ____ free energy are converted to molecules with ____ free energy; therefore, they require a net input of energy in order to proceed.

A) higher; lower
B) lower; higher
C) zero; lower
D) higher; zero
E) potential; kinetic

Endergonic Reactions

Chemical reactions that require an input of energy to proceed, as the products have a higher free energy than the reactants, often associated with anabolic processes in living organisms.

Free Energy

A thermodynamic quantity equivalent to the capacity of a system to do work; used to predict the direction of chemical reactions.

Reactants

Substances initially present in a chemical reaction that are consumed during the reaction to make products.
