What is the net gain of ATP during glycolysis?
A
1
B
2
C
4
D
34
Explanation: 

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: -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: -Hint: 4 ATPs are produced and 2NADPH are produced in glycolysis.

Detailed explanation-4: -The final product of glycolysis is pyruvate in aerobic settings and lactate in anaerobic conditions. Pyruvate enters the Krebs cycle for further energy production.

Detailed explanation-5: -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.
