Glycolysis: 2 ATP per molecule of glucose Total ATP yield of aerobic respiration (including glycolysis): 36 ATP per molecule of glucose (theoretical, less in reality due to leaking of protons across the mitochondrial inner membrane)
In prokaryotes, the breakdown of one molecule of glucose through glycolysis produces a net yield of 2 ATP molecules.
The starting molecules for glycolysis are glucose and two ATP molecules. Glucose is broken down into two molecules of pyruvate through a series of enzymatic reactions, producing energy in the form of ATP and NADH.
4 molecules of ATP are produced per molecule of glucose in glycolysis, but 2 are needed (used, degraded, etc.) to start the reaction, so there is really only a net gain of 2 ATP in the process of glycolysis.
Aerobic metabolism produces a net yield of around 30-32 ATP molecules per glucose molecule. This occurs through glycolysis, the citric acid cycle, and oxidative phosphorylation in the electron transport chain.
Glycolysis yields a net of 2 ATP molecules per glucose molecule.
Gross yield of ATP during glycolysis: 4Net yield of ATP during glycolysis: 2 (anaerobic glycolysis of a glucose molecule took 2 ATP to accomplish so subtract 2 ATP from your gross yield of 4...therefore it's 2 for net yield).Kreb cycle: produces a total of 2ATP (one each time it happens and it happens twice).
In glycolysis, one glucose molecule produces a net yield of two ATP molecules at the end of the process.

In prokaryotes, the breakdown of one molecule of glucose through glycolysis produces a net yield of 2 ATP molecules.
During glycolysis, the overall gain of ATP per glucose molecule is 2. While glycolysis produces 4 ATPs, it uses 2 ATPs in the process.
The molecule needed to start glycolysis is glucose. Glucose is a simple sugar that serves as the initial substrate for the glycolytic pathway, which then breaks down glucose into smaller molecules to produce energy in the form of ATP.
During glycolysis it makes a net amount of 2 molecules of ATP. Fermentation happens anaerobically (without oxygen) and the reduction of pyruvate into lactate itself does not yield any ATP. But I think the answer you are looking for is 2 ATP.
One molecule of sucrose can be broken down into glucose and fructose, both of which can then enter glycolysis to produce ATP. Overall, the breakdown of 1 molecule of sucrose yields about 30-32 ATP.
Glycolysis is a 10 step enzymatically catalyzed reaction which splits up a glucose molecule into two molecules of pyruvate. The process of glycolysis can occur in absence of oxygen. A net yield of 2 ATP is obtained at the end of gylcolysis for every molecule of glucose oxidized.
The starting molecule for glycolysis is glucose. Glucose is a simple sugar that enters the glycolysis pathway to be broken down into smaller molecules, generating energy through a series of chemical reactions.
