Substrate-level phosphorylation directly generates atp during a chemical reaction. as a single molecule of glucose is completely oxidized, in the presence of oxygen, how many molecules of atp are gained by substrate-level phosphorylation? a) 6 atpb) 4 atpc) 2 atpd) 38 atp

B) 4 ATP

Explanation:

The most favoured substrate of the cellular respiration is called glucose which on complete oxidation yields ATP.

The substrate level of phosphorylation is the formation of the ATP molecules from a phosphorylated intermediate and the ADP.

During glycolysis, the substrate-level phosphorylation produces 4 ATP molecules out of which 2 molecules are utilized during the process itself thus there is a net gain of glycolysis produces 2 ATP molecules.

Thus,  4 ATP is the correct answer.
