Cellular Respiration:The process by which cells break down glucose and other molecules to produce ATP, involving glycolysis, the Krebs cycle, and the electron transport chain.
Krebs Cycle:A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats, and proteins into carbon dioxide and water.
Electron Transport Chain:A series of protein complexes that transfer electrons from electron donors to electron acceptors via redox reactions, coupled with the transfer of protons across a membrane, to generate ATP
