d. Metabolic
[expand title=”View Answer ” ] Answer: a. Exergonic  [/expand]
[expand title=”Explanation” ] Explanation:-
Exergonic reactions are biochemical reactions that result in a net release of free energy. During these reactions, the products have lower energy content than the reactants, and the excess energy is released into the surrounding environment. This release of free energy enables the cell to perform work and drive other cellular processes.
In exergonic reactions, the overall change in Gibbs free energy (ΔG) is negative, indicating that the reaction is spontaneous and favors the formation of products. These reactions are crucial for providing energy to fuel various cellular activities, such as muscle contractions, active transport of molecules across cell membranes, and synthesis of cellular components. One example of an exergonic reaction is the breakdown of glucose in cellular respiration, where the energy stored in glucose is released to produce ATP (adenosine triphosphate) molecules that power cellular functions.
