The main product of cellular respiration is adenosine triphosphate (ATP). Cellular respiration is a biochemical process wherein cells convert glucose and oxygen into energy. During this process, glucose undergoes a series of metabolic reactions, including glycolysis, the Krebs cycle, and the electron transport chain, resulting in ATP production. ATP serves as the primary energy currency of the cell, powering various cellular functions, including movement, transport, and biosynthesis. Understanding cellular respiration is essential in biology, medicine, and biochemistry for grasping how organisms harness energy for growth and survival.
