Oxidation of G3P occurs by the removal of hydrogen atoms are picked up by NAD+, and NADH+H+ results. Later the NADH will pass on electrons to the electron transport chain. Oxidation of G3P and subsequent substrtes result in four high energy phosphate groups and these are used to synthesize four ATP. So basically substrate-level ATP synthesis is when an enzyme passes a high-energy phosphate to ADP and ATP results.
Glycolysis, where ADP plus phosphate form ATP. Citric Acid Cycle also has substrate phosphorylation when GDP+Pi forms GTP, which by simple conversion forms ATP.
Just the net gain of ATP that happens during glycolysis and the Krebs cycle. As opposed to oxidative phosphorylation happening during processes along the electron transfer chain.
I believe it occurs in the cytoplasm of mitochondria or chloroplasts.
Production of ATP by transferring phosphates directly from metabolic products to ADP
Substrate-level phosphorylation is when during glycolysis and the Kreb's Cycle an addition of a free phosphate to ADP to form ATP by direct donation.
Enzymes preform this phosphorilation in glycolysis and the citric acid cycle. ADP has one phosphate group attached to it and becomes, by phosphorilation, ATP.
In the sense that substrate level phosphorylation takes place in both these metabolic processes.
Substrate-level phosphorylation is a chemical reaction. The chemical reaction may result in the products ATP or GTP. The resulting product is dependent on the chemicals involved.

ATP
Phosphorylation. It can be done by direct transfer of phosphate group (substrate-level phosphorylation), by the use of proton gradient (oxidative phosphorylation), or by using sunlight (photophosphorylation).
During the pay-off phase of glycolysis.During the Krebs phase, ATP is produced directly by substrate-level phosphorylation. ATP stands for adenosine triphosphate.
Active site
This is anaerobic respiration, also called fermentation or substrate level phosphorylation
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.
ATP is produced by substrate level phosphorylation during glycolisis. There is no oxidative phosphorylation in fermentation since it's an anaeorobic respiration.
ATP
That transfer is called phosphorylation.
100%. Substrate level phosphorylation accounts for about 10% of ATP generated by respiration. The other 90% is generated by oxidative phosphorylation.
Glycolysis and Citric Acid Cycle (Krebs Cycle) form ATP directly in the Substrate Level of Phosphorylation

substrate level phosphorylation
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.
