Final answer:
Respiration is a crucial exothermic redox reaction in biological systems that converts glucose and oxygen into ATP, water, and carbon dioxide through oxidative processes within the cell.
Step-by-step explanation:
The process of respiration is an essential biological phenomenon involving a series of metabolic reactions to convert biochemical energy from nutrients into adenosine triphosphate (ATP), releasing carbon dioxide and water as byproducts. This process is an example of an exothermic redox reaction, where oxygen is reduced and organic compounds such as glucose are oxidized. The overall chemical reaction for cellular respiration involves one molecule of glucose (C6H₁₂O6) and six molecules of oxygen (O₂) reacting to produce six molecules of carbon dioxide (CO₂), six molecules of water (H₂O), and energy in the form of ATP. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.
