Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If Fructose-1, 6-BisPhosphate is put through glycolysis the net result would be:
A
2 ATP
B
4 ATP
C
4 NADH
D
2 FADH2
Explanation: 

Detailed explanation-1: -One molecule of ATP is utilised when glucose is converted to glucose-6-phosphate and the other is utilised when fructose-6-phosphate is converted to fructose-1, 6-bisphosphate. So, the net gain of ATP molecules during glycolysis is 2.

Detailed explanation-2: -One glucose molecule yields four ATP molecules in total during glycolysis. Since 2 ATP molecules are used up in the first phase of glycolysis, there is a net gain of 2 ATP molecules.

Detailed explanation-3: -For complete oxidation of one molecule of Fructose 1, 6-bis phosphate, 38 ATP are produced.

Detailed explanation-4: -Results of Glycolysis The energy to split glucose is provided by two molecules of ATP. As glycolysis proceeds, energy is released, and the energy is used to make four molecules of ATP. As a result, there is a net gain of two ATP molecules during glycolysis.
