Question

Read the following statements and select the correct ones.
(i) PS I is involved in non-cyclic
photophosphorylation only.
(ii) PS II is involved in both cyclic and non-cyclic photophosphorylation.
(iii) Stroma lamellae membranes possess
PS I only, whereas grana lamellae membranes possess both PS I and PS II.

• A. (i) only
• B. (ii) only
• C. (iii) only
• D. (i), (ii) and (iii)

Answer 1

The correct option is C (iii) only

PS-I is involved in both non-cyclic and cyclic photophosphorylation.
PS-II is involved in non-cyclic
photophosphorylation only.
Stroma lamellae membranes possess PS-I only, whereas grana lamellae membranes possess both PS-I and
PS-II.
