Question

Choose the correct answers from the alternatives given :
An exergonic reaction is

• A. a spontaneous reaction in which energy is given off
• B. an uphill reaction requiring input of energy
• C. an oxidation reaction
• D. an anaerobic reaction

Answer 1

Answer: (A)

An exergonic reaction is a process in which energy is released in the form of heat because of the breakage of bonds. They are also called catabolic reactions in which complex substances are broken down into simpler ones. They mostly occur spontaneously but few reactions are there which may occur non-spontaneously. As the reactants lose energy, Gibbs free energy will become negative.

So, the correct option is ' a spontaneous reaction in which energy is given off'.
