why do cells engage in catabolism
Catabolism (breaking larger molecules down into smaller ones) is important for several reasons: (1) Catabolism breaks large complex molecules into smaller, simpler molecules that can then be used (in anabolism) as building blocks for the more complex molecules that cells need to build and repair themselves.n metabolism, your cells use enzymes to precisely control the complicated multi-step chemical reactions that keep you alive. There are two main parts to metabolism: catabolism and anabolism. In catabolism, larger molecules are broken down into smaller molecules, releasing energy.
