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: -Catabolism breaks down large molecules (such as polysaccharides, lipids, nucleic acids, and proteins) into smaller units (such as monosaccharides, fatty acids, nucleotides, and amino acids, respectively). Catabolism is the breaking-down aspect of metabolism, whereas anabolism is the building-up aspect.

Detailed explanation-3: -Catabolism is the set of metabolic processes that break down large molecules. These more complex molecules are broken down to produce energy necessary for various functions of the body. The energy is utilized for building or anabolic processes.

Detailed explanation-4: -During catabolic reactions, proteins are broken down into amino acids, lipids are broken down into fatty acids, and polysaccharides are broken down into monosaccharides. These building blocks are then used for the synthesis of molecules in anabolic reactions.

Detailed explanation-5: -Catabolism is the part of the metabolic process that breaks down large, complicated molecules into smaller ones in order to produce energy. The energy is released as a result of the destructive branch of metabolism.
