Description : Respiration is regarded as a – (1) Synthetic Process (2) Catabolic Process (3) Anabolic Process (4) Reduction Process
Last Answer : (2) Catabolic Process Explanation: Cellular respiration is a catabolic process because it is breaking down glucose to eventually transfer energy into its usable form in ATP. An anabolic process builds things up, photosynthesis is a version of this and the metabolic opposite of cellular respiration.

Description : Contrast and compare exergonic reactions versus endergonic reactions. Which reaction type matches with anabolic reactions? Which matches with catabolic reactions?
Last Answer : Exergonic is when energy is released. In contrast, endergonic requires energy; it absorbs free energy. Magnitude of ΔG for an exergonic reaction represents the max amount of work a reaction can ... In that train of thought, endergonic would match with anabolic, as energy is consumed/required.
