Question

Identify a, b, c and d in the given figure

• A. a. - PS I, b. - Cyt-$b_6/f$ , c. -PS II, d. -ATP synthase
• B. a. - PS II, b. -Cyt-$b_6/f$ , c. -PS I, d. - ATP synthase.
• C. a. - PS I, b. - PQ, c. - ATP synthase, d. - Cyt-$b_6/f$
• D. a. - PS II, b. - ATP, c.-Cyt-$b_6/f$ , d. -$F_0-F_1$ complex

Answer 1

The correct option is B

a. - PS II, b. -Cyt-$b_6/f$ , c. -PS I, d. - ATP synthase.

In thylakoid membrane, components involved in photochemical or light-dependent reactions are present. They are PS-II which oxidises water, the cyt-$b_6/f$ complex which acts as a proton pump, PS-I that reduces $NAD{P}^{+}$ and ATP synthase which, forms ATP.
