glycolysis

The first stage of cellular respiration is glycolysis. It is an anaerobic process that is initiated by 2 ATP molecules and a glucose molecule. The end products are 2 NADH molecules, 2 molecules of pyruvic acid, and a net gain of 2 ATP molecules.
Glycolysis primarily occurs in the cytoplasm of the cell. It involves various enzymes such as hexokinase, phosphofructokinase, and pyruvate kinase. Glycolysis also requires substrates like glucose and ATP, and produces molecules such as pyruvate, ATP, and NADH.
2Actually it produces four. But two are used in the mechanism
That is correct. In glycolysis, glucose is broken down into two molecules of pyruvate, generating a net of 2 ATP and 2 NADH molecules.
The end products of glycolysis are two molecules of pyruvate, two molecules of ATP (net gain), and two molecules of NADH.
2 ATP + 2 NADH + 2 H2O + 2 pyruvate
Glycolysis, the first stage of cellular respiration, produces 2 NADH molecules, 4 ATP molecules (net gain of 2 ATP after subtracting the energy used), and two pyruvate molecules from one molecule of glucose.
2 NADH, 2 H+, 2 pyruvate, 2 ATP, and 2 H2O
Water is not a product of glycolysis. Glycolysis produces 2 molecules of pyruvate, 2 molecules of NADH, and also 2 molecules of ATP.
The product of glycolysis is pyruvic acid.
Glycolysis produces 2 pyruvate, 2 NADH, and 2 ATP [net]
The Krebs cycle produces NADH, ATP, and two pyruvate molecules. The electron transport chain generates a large amount of ATP by oxidative phosphorylation. The Calvin cycle is involved in carbon fixation during photosynthesis. Glycolysis, on the other hand, is a metabolic pathway that breaks down glucose to produce ATP and pyruvate.
NADH and ATP
Glycolysis produces ATP (energy), pyruvate, and NADH. ATP is used as the primary energy source for cellular processes, pyruvate can be further metabolized to produce more ATP or other molecules, and NADH can be used in the electron transport chain to generate additional ATP.

For each mole of pyruvate, the Krebs cycle produces 3 molecules of NADH, 1 molecule of FADH2, and 1 molecule of ATP. Therefore, from 2 moles of pyruvate, the Krebs cycle produces 6 molecules of NADH, 2 molecules of FADH2, and 2 molecules of ATP. These NADH and FADH2 molecules go on to generate more ATP through oxidative phosphorylation in the electron transport chain.
