Question

Number of reduced co-enzymes produced from one sucrose molecule in aerobic respiration is (1) 18 (2) 24 (3) 12 (4) 14. Explain.

Answer 1

24  reduced co-enzymes are produced from one sucrose molecule in aerobic respiration.

NADH and FADH₂ are produced. The break-up is as follows:

During Gycolysis - 2NADH
Oxidative decarboxylation of pyruvate - 2NADH
Kreb's Cycle - 6NADH and 2FADH₂

The total no of co-enzymes from one glucose molecule is 12. Since one glucose molecule has two monosaccharides, so there are 24 co-enzymes produced.
