Options

  1. AA-III, B-I, C-IV, D-II
  2. BA-I, B-III, C-IV, D-II
  3. CA-III, B-I, C-II, D-IV
  4. DA-IV, B-I, C-III, D-II

Correct answer

A. A-III, B-I, C-IV, D-II

Step-by-step solution

Non-cyclic photophosphorylation involves both PS I and PS II and results in the synthesis of both ATP and NADPH. The biosynthetic phase (dark reaction) is the stage where CO ₂ is reduced to carbohydrates, consuming the ATP and NADPH produced in the light reaction. The splitting of water is associated with PS II and results in the release of O ₂ , protons ( H^+ ), and electrons. Cyclic photophosphorylation involves only PS I and results in the synthesis of ATP only, without the production of NADPH or release of O ₂
