Explanation:
Detailed explanation-1: -In 6th and 9th steps of glycolysis 4 ATP molecules (two from each 3-phosphoglyceraldehyde molecule) are formed and two ATP molecules are consumed in the first and third steps of glycolysis.
Detailed explanation-2: -From one glucose molecule, 4 ATP molecules are produced in glycolysis with an addition of 2 NADH molecules out of which 2 ATP molecules are used in the first half of glycolysis as a total gain of 2 ATP molecules. Glycolysis is a 10-step process in which steps 7 and 10 produce 4 molecules of ATP. More items
