Answer #1

Substrate level Phosphorylation (SLP) is the formation of ATP or DP by direct transfer of PO3 to the ADP and GDP .

Its an metabolic reaction in which oxidation and phosporylation is not coupled (which is generally the process of ATP generation)

It uses the phosphorylated compound directly to form the ATP or GTP .

In glycolysis , the process in which 3-phosphoglyceraldehyde is coverted to 1,3-bisphosphoglycerate via glyceraldehyde 3-phosphate dehydrogenase, is the process at which SLP occurs.

So the correct answer is 1,3-bisphosphoglycerate
