Metabolism is the set of ilfe-sustaining chemical transformations within the cells of living organisms. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments.
Metabolism is a dynamic process. The cell is continuously degrading and synthesizing molecule s. In general, the catabolic pathways are providing energy in the form of ATP that is used to drive the anabolic processes. Explain turnover rate and optimum conditions as related to enzymes.
