Summary Introduction
Introduction:
Several reactions are very crucial for the generation of energy to power up the cellular machinery and systems in the human body. Some examples of such reactions are glycolysis, tricarboxylic acid cycle, and electron transport chain. The main purpose of these reactions is to yield energy.
