  1. Question 1

    Q1. During the conversion of 1,3-bisphosphoglycerate to 3-phosphoglycerate in glycolysis, ATP is produced. What is the name of this specific mechanism of ATP generation?

    • A) Oxidative phosphorylation
    • B) Photophosphorylation
    • C) Substrate-level phosphorylation
    • D) Chemiosmotic phosphorylation

    Answer: Substrate-level phosphorylation

    Explanation: Substrate-level phosphorylation occurs in glycolysis when a phosphate is directly transferred to ADP; oxidative phosphorylation requires a proton gradient and ATP synthase.
