In aerobic respiration, which occurs in the presence of oxygen, glucose is completely broken down into carbon dioxide (CO\u2082), water (H\u2082O), and a large amount of energy (ATP). This process occurs in aerobic tissues of organisms, including humans. Option A is incorrect because not all organisms perform aerobic respiration (e.g., anaerobic bacteria, yeast under anaerobic conditions). Option B is incorrect because muscle cells produce lactate during anaerobic conditions, not ethanol and CO\u2082. Option D is incorrect because yeast produces ethanol and CO\u2082 during alcoholic fermentation, not lactate.<\/section>\n
Aerobic respiration yields the maximum amount of energy from glucose and results in CO\u2082 and H\u2082O as final products. Anaerobic respiration (fermentation) yields less energy and produces different products like lactate or ethanol.<\/section>\n
The overall equation for aerobic respiration is C\u2086H\u2081\u2082O\u2086 + 6O\u2082 \u2192 6CO\u2082 + 6H\u2082O + Energy (ATP). This process involves glycolysis (cytoplasm), the Krebs cycle (mitochondrial matrix), and the electron transport chain (inner mitochondrial membrane).<\/section>\n","protected":false},"excerpt":{"rendered":"
