Solution
The correct option is A 4
Sucrose is a disaccharide made up of glucose and fructose. Two glucose molecules form four molecules of pyruvate during glycolysis. One molecule of pyruvate means one round TCA cycle. Here, four molecules of pyruvate mean four rounds of TCA cycle. So, the correct option is "4".
