Quizplus · Accepted Answer

Metabolism refers to all chemical reactions that occur within a cell, including the processes that break down molecules to release energy (catabolic reactions) and those that build up molecules using energy (anabolic reactions). While enzymes are essential for these reactions to occur, they are not the sum of all reactions themselves. ATP is a molecule that stores and transfers energy within a cell, but it is not the sum of all energy usage within a cell. Vitamins are essential organic compounds that a cell requires to function, but they are not directly related to metabolism.
