Detailed explanation-1: -A fundamental task of proteins is to act as enzymes-catalysts that increase the rate of virtually all the chemical reactions within cells.
Detailed explanation-2: -CATABOLIC reactions BREAK DOWN food molecules and release energy and chemicals for further use. ANABOLIC reactions BUILD UP complex molecules required by the cell. Anabolic reactions depend on catabolic reactions to provide energy and materials. METABOLISM is the working together of catabolic and anabolic reactions.
