Question

Arrange the different phases of photosynthesis in the correct sequence. A. Capturing the solar energy B. Formation of higher-energy organic intermediates C. Splitting of water and release of oxygen D. Fixation of CO2 into 3-phosphoglycerate E. Reduction of phosphoglycerate into glyceraldehyde-3-phosphate. Choose the correct answer from the options given below:

• A. A, B, C, D, E
• B. A, C, B, D, E
• C. A, B, D, E, C
• D. B, A, C, D, E

Hint:

Remember the sequence: Light absorption, water splitting, energy transfer, carbon fixation, and sugar formation.

Answer 1

The Correct Option is B

Step 1: Concept
Photosynthesis

Step 2: Meaning
The process by which plants convert light energy into chemical energy to fuel their activities.

Step 3: Analysis
Option B (A, C, B, D, E) is correct. The sequence of photosynthesis phases follows the order of light-dependent reactions and Calvin cycle.

Step 4: Conclusion
A represents the absorption of light energy by chlorophyll; C describes the splitting of water molecules and release of oxygen; B involves the formation of high-energy electron carriers; D pertains to carbon fixation into 3-phosphoglycerate during the Calvin cycle; E completes the cycle with the reduction of phosphoglycerate. Final Answer: (B)
