Overview of Aerobic Respiration
Aerobic respiration is the process by which cells convert glucose into energy in the presence of oxygen. This process occurs in several stages: glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain.
ATP Production Breakdown
- Glycolysis:
- Occurs in the cytoplasm.
- Produces 2 ATP directly and 2 NADH.
- Each NADH can yield approximately 2.5 ATP in the electron transport chain.
- Krebs Cycle:
- Occurs in the mitochondria.
- Produces 2 ATP directly, 6 NADH, and 2 FADH2.
- Each NADH yields about 2.5 ATP and each FADH2 yields about 1.5 ATP.
- Electron Transport Chain:
- Takes place in the inner mitochondrial membrane.
- Total ATP yield from NADH (from glycolysis and Krebs):
- 8 NADH x 2.5 ATP = 20 ATP
- Total ATP yield from FADH2:
- 2 FADH2 x 1.5 ATP = 3 ATP
Calculating the Net Gain
- Total ATP Yield:
- From Glycolysis: 2 ATP (direct) + 5 ATP (from 2 NADH)
- From Krebs Cycle: 2 ATP (direct) + 15 ATP (from 6 NADH) + 3 ATP (from 2 FADH2)
- Final Calculation:
- Total = 2 + 5 + 2 + 15 + 3 = 27 ATP
However, if we include the ATP used for transporting the NADH produced in glycolysis into the mitochondria, the net gain adjusts to 36 or 38 ATP depending on the shuttle mechanism used.
Conclusion
Thus, the net gain of ATP molecules during aerobic respiration of one molecule of glucose can be considered as 38 ATP, making option 'D' the correct choice.
