Question

Identify the incorrect match:

Hint:

Light reactions → ATP & NADPH; Dark reactions → sugar synthesis.
Associate each process with correct products to avoid confusion.
Remember photophosphorylation = ATP generation only.

Answer 1

1. Photophosphorylation produces ATP and NADPH, not hexose sugar.
2. Hexose sugar is synthesized during the Calvin cycle (carbon fixation).
3. Proton gradient → ATP synthesis, C3 plants → 3-PGA, PEP carboxylase → OAA are all correct.
4. Hence incorrect match is (3) Photophosphorylation - Hexose sugar synthesis.
