Question

If maltose is used as the respiratory substrate instead of glucose, the output from aerobic respiration of every molecule of maltose would be

• A. 2 mol.each of ethanol, CO₂ and ATP
• B. 4 mol. each of ethanol, CO₂ and ATP
• C. 38 mol. of ATP, 6 mol each of H₂O and CO₂
• D. 76 molecules of ATP, 12 mol. each of water and CO₂

Answer 1

The correct option is D

76 molecules of ATP, 12 mol. each of water and CO₂

Maltose is a disaccharide of glucose. If maltose is used as the respiratory substrate instead of glucose, the output from aerobic respiration of every molecule of maltose would be 76 molecules of ATP, 12 mol. each of water and $C{O}_2$.
