List IList II
P. PS II1. Reduces NADP+
Q. NADP reductase2. Water-splitting complex
R. CF03. Proton channel in membrane
S. CF14. Catalyses ATP formation

  • (a) P-2, Q-1, R-3, S-4 Correct
  • (b) P-3, Q-4, R-2, S-1 Your answer
  • (c) P-2, Q-1, R-4, S-3 Your answer
  • (d) P-1, Q-2, R-3, S-4 Your answer
Your answer: Correct answer: (a)

Explanation

Why (a) is correct

PS II is linked to the water-splitting complex (2); NADP reductase reduces NADP+ (1); CF0 is the proton channel (3); CF1 catalyses ATP formation (4). So P-2, Q-1, R-3, S-4.

Why the other options are wrong

  • (b) · your answer This mixes up all four pairs.
  • (c) · your answer This swaps CF0 and CF1.
  • (d) · your answer This swaps PS II and NADP reductase.
NCERT point: CF0 in the membrane; CF1 projecting into the stroma.
