One molecule of sucrose = one glucose + one fructose
Fructose is converted into glucose before it enters the respiratory cycle.
One molecule of glucose on breakdown yields 36 ATP on cellular respiration.
Then two molecules of glucose yields 72 ATP molecules of ATP on cellular respiration

64 ATP are produced from one molecule of sucrose during aerobic cellular respiration.
Explanation:
Sucrose is a disaccharide. It contains 2 monosaccharides: one glucose molecule and one fructose molecule.
- Fructose is converted into glucose by the process of gluconeogenesis.
- So from one molecule of sucrose, we get 2 molecules of glucose.
From 1 molecule of glucose 7 ATP is produced from Glycolysis.
- That is 4ATP + 5 ATP - 2ATP = 7 ATP
- 2 molecules of pyruvates are produced from 1 molecule of glucose by glycolysis.
From facts of glycolysis, 5ATP is produced.
So from 2 molecules of pyruvates, 20 ATP is produced from by 2 TCL cycle.
- 2 TCL cycle = 2(1 ATP + 3NADH + 1 FADH2)
- one molecule of FADH2 = 1.5 ATP
- one molecule of NADH = 2.5 ATP
- Total ATP from 2 TCL cycles is 20
Total 32 ATP (7+5+20) are obtained per glucose in cytoplasm through respiratory chain.
So total 64 ATP(32+32) are produced from one molecule of sucrose during aerobic cellular respiration.
