Metabolism is the sum of all chemical reactions taking place within the cells in the body. The chemical reactions follow a metabolic pathway in which the product of one reaction is the starting substance for the next reaction Integration Of Metabolism Metabolism Consist of Highly Interconnected Pathways The basic strategy of catabolic metabolism is to form ATP, NADPH , and building blocks for biosyntheses. 1.

Glucose is a primary source of energy for humans. The nervous system, including the brain, totally depends on glucose for energy. . The liver, pancreas, and other endocrine glands are all involved in controlling the blood glucose concentrations within a narrow range. .
