Detailed explanation-1: -During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi–> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation.
Detailed explanation-2: -Therefore, the net gain of ATP in glycolysis in aerobic organisms is 8 ATP.
Detailed explanation-3: -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-4: -The 8 GTP are transformed into 8 ATP. This gives us a total of 108 ATP molecules. However, since 2 ATP molecules were used up in the activation of the fatty acid, this means that 106 ATP molecules are generated when a single palmitic acid is broken down via beta oxidation.
