Which of the following statements is incorrect?

  1. A
    Grana lamellae have both PS I and PS II
  2. B
    Cyclic photophosphorylation involves both PS I and PS II
  3. C
    Both ATP and NADPH + H+ are synthesized during non-cyclic photophosphorylation
  4. D
    Stroma lamellae have PS I only and lack NADP reductase

Solution & Step-by-step Explanation

Shutterstock Explore Grana (stacked membranes) contain both photosystems.Incorrect statement: Cyclic photophosphorylation involves only PS I. Electrons travel in a closed loop, and only ATP is synthesized.Non-cyclic involves both PS I and PS II and produces both ATP and NADPH.Stroma lamellae lack PS II and NADP reductase.
