Which of the following is correct about light reaction?
1 It occurs in the Grana
2 ATP and NADPH are produced
3 Chlorophyll gets oxidised
4 All of these
Explanation:
Light reaction occurs in the lumen of thylakoid of a granum. Here, chlorophyll gets oxidised converting light energy to chemical energy. Its end products are ATP and NADPH which are further used in dark reactions.

Along with the electrons that come from the electron acceptor of ______ protons are necessary for the reduction of _______
1 PS-II, \(NAD{P^ + }\)
2 PS-I, \(NAD{P^ + }\)
3 PS-II, NADPH
4 PS-I, NADPH
Explanation:
In non-cyclic photophosphorylation, PS-I requires electrons (from primary electron acceptor ferredoxin) and protons (from photolysis of water) both to reduce NADP+ to NADPH+\({H^ + }\)

Which of the following statements is incorrect?
1 Both ATP and \(NADP{H^ + }\;{H^ + }\) are synthesized during non-cyclic photophosphorylation.
2 Stroma lamellae have PS I only and lack NADP reductase.
3 Grana lamellae have both PS I and PS II.
4 Cyclic photophosphorylation involves both PS I and PS II.
Explanation:
Cyclic photophosphorylation involves only with PSI whereas noncyclic photophosphorylation is with both PSI and PSII.
