What does the “substrate” in substrate level phosphorylation tell you?

Substrate-level phosphorylation is a metabolic reaction that results in the formation of ATP or GTP by conversion of a higher energy substrate (whether phosphate group attached or not) into lower energy product and a using some of the released chemical energy, the Gibbs free energy, to transfer a phosphoryl (PO3) group to ADP or GDP from another phosphorylated compound. Hope this is fine for you✌️

Bruh i don’t know the answer tbh but you can google it
