Answer:
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.
