Detailed explanation-1: -2 molecules of ATP are utilised in the glycolysis. 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: -Glycolysis is actually a series of ten chemical reactions that requires the input of two ATP molecules. This input is used to generate four new ATP molecules, which means that glycolysis results in a net gain of two ATPs.
