Just two.
Four are produced by substrate level phosphorylation but two ATP are needed in the energy investment phase of glycolysis.
During glycolysis, the overall gain of ATP per glucose molecule is 2. While glycolysis produces 4 ATPs, it uses 2 ATPs in the process.
A cell can gain a net total of 2 molecules of ATP through glycolysis. This occurs when one molecule of glucose is broken down into two molecules of pyruvate.

Glycolysis produces a net gain of 2 ATP molecules for each reaction
The cell can produce a net gain of 2 ATP molecules from a single molecule of glucose through the process of glycolysis. This occurs during the conversion of glucose to pyruvate.
2 molecules of ATP from each glucose molecule.
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.
In aerobic respiration, one glucose molecule typically produces 36-38 ATP molecules through glycolysis, the Krebs cycle, and the electron transport chain. In anaerobic respiration, such as fermentation, the number of ATP molecules produced is lower, around 2 ATP molecules.
The net gain of ATP at the end of glycolysis is 2 molecules of ATP.
4, but two are used in the process, so there is a net gain of 2
During glycolysis, ATP is synthesized through a series of enzymatic reactions that break down glucose into pyruvate. Specifically, ATP is generated through substrate-level phosphorylation, where a phosphate group is transferred from a high-energy molecule to ADP to form ATP. This process occurs at two key steps in glycolysis: the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate and the conversion of phosphoenolpyruvate to pyruvate. Overall, glycolysis produces a net gain of 2 ATP molecules per glucose molecule.
