Detailed explanation-1: -Glycolysis occurs in both aerobic and anaerobic states. In aerobic conditions, pyruvate enters the citric acid cycle and undergoes oxidative phosphorylation leading to the net production of 32 ATP molecules.

Detailed explanation-2: -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.

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: -Glycolysis produces only two net molecules of ATP per 1 molecule of glucose. However, in cells lacking mitochondria and/or adequate oxygen supply, glycolysis is the sole process by which such cells can produce ATP from glucose.

Detailed explanation-5: -There is a net gain of 2 ATP as a result of glycolysis. The reason for this is because the first part of glycolysis requires an input of 2 ATP. The second part of glycolysis produces 4 ATP.
