Class 1. Common pathways of catabolism 1. Define metabolism and its role. __

Metabolism refers to the set of all chemical reactions that occur within an organism to maintain life. These reactions are organized into two main categories: catabolism and anabolism. Catabolism involves the breakdown of complex molecules into simpler ones, releasing energy in the process. Anabolism, on the other hand, involves the synthesis of complex molecules from simpler ones, requiring energy input. Metabolism plays a crucial role in the body by providing the energy and building blocks necessary for various cellular processes, including growth, repair, and maintenance.
