LIFE SCIENCE

Detailed explanation-1: -Catabolism (pronounced: kuh-TAB-uh-liz-um), or destructive metabolism, is the process that produces the energy needed for all activity in the cells. Cells break down large molecules (mostly carbs and fats) to release energy.

Detailed explanation-2: -Anabolism and Catabolism: Catabolic reactions release energy, while anabolic reactions use up energy. Anabolism is the opposite of catabolism. For example, synthesizing glucose is an anabolic process, whereas the breaking down of glucose is a catabolic process.

Detailed explanation-3: -Catabolism is the break down of complex molecules. Catabolism is the breakdown of complex substances to their constituent parts (glucose, amino acids and fatty acids) which form substrates for metabolic pathways.

Detailed explanation-4: -Catabolism is referred to as a series of metabolic pathways that are involved in the conversion of macromolecules into simpler molecules or monomers.
