NEET Botany Calvin Cycle MCQ Question
Which of the following statements about the Calvin Cycle is correct?
The Calvin Cycle occurs in mesophyll cells of C3 plants and bundle sheath cells of C4 plants.
The first stable product of CO2 fixation in the Calvin Cycle is always a C4 acid.
The Calvin Cycle requires 6 ATP and 6 NADPH to synthesize one glucose molecule.
RuBisCO is not involved in the Calvin Cycle and is absent in C3 plants.
Correct Answer
Detailed Explanation
The Calvin Cycle occurs in the mesophyll cells of C3 plants and in the bundle sheath cells of C4 plants, as stated in the context. Option B is incorrect because the first product in C3 plants is a C3 acid (PGA), not a C4 acid. Option C does not accurately represent the ATP and NADPH requirements, and Option D is false as RuBisCO is essential for the cycle.
