NEET Botany Light Reaction MCQ Question
Which of the following statements about the light reactions of photosynthesis is/are correct?
Non-cyclic photophosphorylation involves both PS II and PS I working in series.
Cyclic photophosphorylation produces both ATP and NADPH.
Accessory pigments help in absorbing a wider range of wavelengths and protect chlorophyll a.
Light reactions occur only in the thylakoid membranes of chloroplasts.
Correct Answer
Detailed Explanation
Statement A is correct as non-cyclic photophosphorylation involves both photosystems. Statement B is incorrect because cyclic photophosphorylation only produces ATP. Statement C is correct as accessory pigments do help in light absorption and protection. Statement D is incorrect since light reactions occur in the thylakoid membranes, not limited to them.
