Detailed explanation-1: -Overall, the process of glycolysis produces a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules for the cell to use for energy.

Detailed explanation-2: -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).

Detailed explanation-3: -Glycolysis produces 4 ATP molecules. However, 2 ATP molecules are required to initiate glycolysis. Subtracting these two numbers gives the net ATP yield from glycolysis–2 ATP molecules.

Detailed explanation-4: -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-5: -In the entire process of glycolysis, 2 NADPH molecules also formed. Each NADH produces 3ATP molecules that mean 6 ATP molecules in glycolysis are produced via NADPH. Therefore the total ATP molecules formed are 10ATP as 2ATPs used up in the initial steps, the net gain is 8 ATP molecules.
