NEETBotanyPhotosynthesis in Higher Plants
Components Functions or Locations A. Phosphoenolpyruvate (PEP) 1. Primary CO2 acceptor in mesophyll cells. B. Bundle Sheath Cells 2. Enzyme responsible for fixing CO2 to PEP. C. PEP Carboxylase (PEPcase) 3. Site of Calvin cycle in C4 plants. D. RuBisCO 4. Enzyme that fixes CO2 in the Calvin cycle and is located in bundle sheath cells.
Options
- AA - 1, B - 3, C - 2, D - 4
- BA - 2, B - 1, C - 4, D - 3
- CA - 3, B - 4, C - 1, D - 2
- DA - 4, B - 3, C - 2, D - 1
Correct answer
A. A - 1, B - 3, C - 2, D - 4
Step-by-step solution
A - 1: Phosphoenolpyruvate (PEP) is the primary CO2 acceptor located in the mesophyll cells. B - 3: The Calvin cycle, which is common to all plants, occurs in the bundle sheath cells of C4 plants. C - 2: PEP Carboxylase (PEPcase) is the enzyme responsible for fixing CO2 to PEP in the mesophyll cells. D - 4: RuBisCO is the enzyme that fixes CO2 in the Calvin cycle and is located in the bundle sheath cells of C4 plants.
