Number of reduced co-enzymes produced from one sucrose molecule in aerobic respiration is
(1) 18
(2) 24
(3) 12
(4) 14
Please explain?
Hi Meemansha,
Please find below the solution to the asked query:
The correct option is (2).
The two reduced co enzymes are NADH and FADH2.
Number of reduced co enzymes produced from one molecule of glucose during aerobic respiration is as under:
Thus, total yield of co enzymes from one glucose molecule is 12.
Since, sucrose is disaccharide made up of two monosaccharides i.e one glucose and one fructose molecule. Hence the total co enzyme yield from it will be 12 x 2 = 24 co enzymes.
Hope this information will clear your doubts about the total yield of co enzymes from one sucrose molecule during aerobic respiration.
If you have any more doubts just ask here on the forum and our experts will try to help you out as soon as possible.

Number of reduced co enzymes produced from one molecule of glucose during aerobic respiration is as under:
| Step | Co enzyme yield |
| Glycolysis | 2 NADH |
| Oxidative decarboxylation of pyruvate | 2 NADH |
| Kreb's cycle | 6 NADH and 2 FADH2 |
| Total yield | 10 NADH + 2 FADH2 = 12 Co enzymes. |
Thus, total yield of co enzymes from one glucose molecule is 12.
