Glycolysis and Citric Acid Cycle (Krebs Cycle) form ATP directly in the Substrate Level of Phosphorylation
ATP in fermentation is typically produced by substrate-level phosphorylation, which involves the direct transfer of a phosphate group to ADP from a phosphorylated substrate. Oxidative phosphorylation, which involves the use of an electron transport chain to produce ATP, is not generally involved in fermentation.
Substrate-level phosphorylation can best be describe as the direct transfer of phosphate from one substrate to another. Oxidative phosphorylation is different from substrate level phosphorylation is that it generates ATP by using a proton motive force.
Substrate-level phosphorylation occurs during Glycolysis and the Kreb's Cycle and involves the physical addition of a free phosphate to ADP to form ATP. Oxidative phosphorylation, on the other hand, takes place along the electron transport chain, where ATP is synthesized indirectly from the creation of a proton gradient and the movement of these protons back accross the membrane through the protein channel, ATP synthase. As the protons pass through, ATP is created.
One molecule of ATP is typically produced during substrate-level phosphorylation. This occurs when a high-energy phosphate group is transferred directly from a substrate molecule to ADP, forming ATP.
ATP is formed from ADP through a process called phosphorylation, which involves adding a phosphate group to ADP. This can occur through two main pathways in cells: substrate-level phosphorylation, where a phosphate group is transferred from a high-energy substrate molecule to ADP, or oxidative phosphorylation, which involves the transfer of electrons through the electron transport chain to generate a proton gradient that drives ATP synthesis by ATP synthase.
100%. Substrate level phosphorylation accounts for about 10% of ATP generated by respiration. The other 90% is generated by oxidative phosphorylation.

substrate level phosphorylation
The transfer of a phosphate group that occurs in glycolysis is called substrate-level phosphorylation. This process involves the direct transfer of a phosphate group from a substrate molecule to ADP to form ATP.

substrate level phosphorylation
In substrate level phosphorylation, the ADP is phosphorylated directly by the transfer of phosphate group from substrate. If we consider glucose, then we get four substrate level phosphorylated ATPs, net gain of two in glycolysis and other two are formed when the two pyruvate molecules formed after glycolysis enter the TCA cycle.
