Exergonic Reactions Release energy.

Exergonic Reactions Release energy.

• A. Exergonic Reactions
• B. Endergonic Reactions
• C. Catabolic Reactions
• D. Anabolic Reactions

Answer: (A)

Energy changes in reactions differentiate exergonic from endergonic processes; exergonic reactions release energy because the free energy of the products is lower than that of the reactants (ΔG < 0). This makes them spontaneous and able to power other cellular work. In metabolism, such energy-releasing steps often come from breaking down nutrients, i.e., catabolic pathways. Endergonic reactions, on the other hand, require an input of energy to proceed (ΔG > 0) and are typically associated with building larger, more complex molecules (anabolic pathways). So the statement that exergonic reactions release energy is correct.
