Read the following statements carefully: (A) The splitting of water is associated with the PS II. (B) Stroma lamellae evolve oxygen during photosynthesis. (C) Cyclic photophosphorylation does not involve photolysis of water. (D) Grana lamellae membranes lack NADP reductase enzyme. How many of the above statements are correct?

Options

  1. AOne
  2. BThree
  3. CFour
  4. DTwo

Correct answer

D. Two

Step-by-step solution

Statement (A) is correct as the water splitting complex is associated with the PS II, which itself is physically located on the inner side of the membrane of the thylakoid. Statement (B) is incorrect because stroma lamellae lack PS II, and therefore cannot perform photolysis of water or evolve oxygen. Statement (C) is correct because cyclic photophosphorylation involves only PS I, whereas photolysis of water is strictly associated with PS II. Statement (D) is incorrect because grana lamellae membranes possess both
