Cellular respiration is a complex process that breaks down glucose to produce ATP through three stages: glycolysis, the Krebs cycle, and the electron transport chain, involving NAD and FAD molecules. It generates energy in the form of ATP by repackaging glucose and producing byproducts like carbon dioxide and water.
Insights
- Cellular respiration converts glucose into energy in the form of ATP through stages like glycolysis, the Krebs cycle, and the electron transport chain, with NAD and FAD molecules playing a critical role in the process.
- Despite textbooks suggesting 38 ATPs are produced, the actual yield from cellular respiration may be around 29-30 ATPs, with the majority being generated in the electron transport chain through the utilization of NADH molecules.
