Which statement correctly compares the malate–aspartate shuttle and the glycerol-3-phosphate shuttle in terms of energy yield per cytosolic NADH?

Which statement correctly compares the malate–aspartate shuttle and the glycerol-3-phosphate shuttle in terms of energy yield per cytosolic NADH?

• A. Both shuttles yield the same ATP per NADH
• B. Malate-aspartate yields ~2.5 ATP per NADH; glycerol-3-phosphate yields ~1.5 ATP per NADH
• C. Malate-aspartate yields ~1.5 ATP per NADH; glycerol-3-phosphate yields ~2.5 ATP per NADH
• D. Malate-aspartate yields ~3.5 ATP per NADH; glycerol-3-phosphate yields ~2.5 ATP per NADH

Answer: (C)
