NEETBotanyPhotosynthesis in Higher Plants
Processes Details A. Calvin Cycle 1. Produces ATP and NADPH, which are used in the biosynthetic phase. B. Light Reaction 2. Uses ATP and NADPH to fix CO2 into sugars. C. Chemiosmosis 3. Creates a proton gradient across the thylakoid membrane to drive ATP synthesis. D. Radioisotope 14C Experiment 4. Used by Melvin Calvin to discover the first CO2 fixation product and the Calvin cycle.
Options
- AA - 2, B - 1, C - 3, 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 - 2, B - 1, C - 3, D - 4
Step-by-step solution
A - 2: The Calvin cycle uses ATP and NADPH to fix CO2 into sugars. B - 1: The light reaction produces ATP and NADPH, which are used in the biosynthetic phase. C - 3: Chemiosmosis creates a proton gradient across the thylakoid membrane to drive ATP synthesis. D - 4: The radioisotope 14C experiment was used by Melvin Calvin to discover the first CO2 fixation product and the Calvin cycle.
