Detailed explanation-1: -There are three main steps of cellular respiration: glycolysis; the citric acid (TCA) or the Krebs cycle; and the electron transport chain, where oxidative phosphorylation occurs. The TCA cycle and oxidative phosphorylation require oxygen, while glycolysis can occur in anaerobic conditions.
Detailed explanation-2: -Thus the correct order of the stages in cellular respiration is: Glycolysis-Oxidative decarboxylation-Krebs cycle-Electron transport chain-Oxidative phosphorylation.
Detailed explanation-3: -Glycolysis – Partial breakdown of Glucose to Pyruvic acid (Anaerobic) Krebs Cycle – Complete oxidation of Pyruvate to release Carbon dioxide (Aerobic respiration) Electron Transport system – Oxidation of NADH and FADH2 to generate ATP.
