Vedclass · Answer

(C) Sucrose is a disaccharide composed of one molecule of glucose and one molecule of fructose.
In aerobic respiration,both glucose and fructose are broken down through glycolysis,the Krebs cycle,and the electron transport system.
One molecule of glucose yields $38$ $ATP$ (assuming the malate-aspartate shuttle).
Since sucrose consists of two hexose sugars,the total energy yield is $38 + 38 = 76$ $ATP$.
Therefore,the net gain of energy from one molecule of sucrose is $76$ $ATP$.

The net gain of energy,from one molecule of sucrose in aerobic respiration,is (in $ATP$)
