2 ATP molecules

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: -In glycolysis, the net gain of ATP molecules is 2. Two ATP per glucose molecule are required to initiate the process, then a total of four ATP are produced per molecule of glucose.
Detailed explanation-3: -Glycolysis: The Foundation of Cellular Respiration This process requires the investment of 2 ATP molecules and yields 4 ATP in addition to the pyruvate and another type of molecule called NADH, which will contribute to the final step of cellular respiration.
Detailed explanation-4: -Thus, two ATPs are used in the first three steps of glycolysis. Hence, to split the glucose 2 molecules of ATPs are used.
