Central metabolism provides mechanisms for the generation of energy from carbon-energy source catabolism and the production of biosynthetic precursors and intermediates for the anabolic pathways essential to maintain cell structure and function.
Food energy + ADP + P â ATP. Catabolic reactions generate energy to make ATP, and the ATP energy is used to drive anabolic. reactions, such as metabolic turnover (replacement of cell parts), growth and cell division, and. special functions (such as secretion, absorption, contraction, or signaling). Metabolism = the sum of all chemical reactions in the body; catabolism + anabolism. All energy production begins in the cytosol of the cell.
