    Question

    In C₃ plants the enzyme involved for formations of

    Glyceric acid –3- phosphate (PGA) is:
    A Acetyl Co-A Correct Answer Incorrect Answer
    B Ribulose biphosphate carboxylase Correct Answer Incorrect Answer
    C Reductase Correct Answer Incorrect Answer
    D None of these Correct Answer Incorrect Answer

    Solution

    RuBisCO is a key enzyme in the Calvin cycle, which is the main pathway of carbon fixation during photosynthesis in C₃ plants. It catalyzes the reaction between ribulose-1,5-bisphosphate (RuBP) and carbon dioxide (CO₂) to form two molecules of 3-phosphoglycerate (PGA).
