Final answer:
From one molecule of glucose processed in aerobic respiration, 36 to 38 ATP molecules are generated. The glycolysis stage contributes 2 ATP, the Krebs cycle adds another 2, and the electron transport chain can yield up to 34 ATP.
Step-by-step explanation:
The answer to the question of how many ATP molecules are generated from one molecule of glucose during aerobic respiration is 36 to 38. During this process, the glycolysis stage produces 2 ATP molecules, and the Krebs cycle generates another 2. When the electron transport chain (ETC) utilizes the NADH and FADH₂ produced in the earlier stages, it can create up to 34 ATP molecules. Considering the conversion equivalents where NADH is roughly 2.5 ATPs and FADH₂ is roughly 1.5 ATPs, the approximate yield of ATP during complete aerobic respiration of glucose is around 32 ATP molecules.
To elaborate, the electron transport chain yields about 3 ATP molecules for every oxidized NADH and 2 ATPs for each oxidized FADH₂ molecule. Despite the theoretical maximum of 38 ATP molecules, the actual number is commonly lower due to energy loss from processes such as the transport of intermediates into the mitochondria in eukaryotic cells.
