Question

Quizplus · Accepted Answer

Metabolism refers to the biochemical reactions that occur in living organisms and involves the conversion of chemical energy (usually stored in nutrients) into work, such as movement or the synthesis of biomolecules. Option B is incorrect as metabolism does not convert mechanical energy into work; rather, it is the other way around. Option C is incorrect as glucose conversion into carbon dioxide is only one metabolic pathway; there are many others that do not involve glucose at all. Option D is incorrect as converting amino acids into proteins is a specific metabolic process, but it does not encompass the entirety of metabolism.
