Explanation:
Detailed explanation-1: -In biochemistry, a metabolic pathway is a linked series of chemical reactions occurring within a cell. The reactants, products, and intermediates of an enzymatic reaction are known as metabolites, which are modified by a sequence of chemical reactions catalyzed by enzymes.
Detailed explanation-2: -Two types of metabolic reactions take place in the cell: ‘building up’ (anabolism) and ‘breaking down’ (catabolism). Catabolic reactions give out energy. They are exergonic. In a catabolic reaction large molecules are broken down into smaller ones.
