NEET Botany Light Reaction MCQ Question
Which of the following statements about the light reaction of photosynthesis is correct?
Non-cyclic photo-phosphorylation involves both PS II and PS I working sequentially.
Cyclic photo-phosphorylation produces both ATP and NADPH + H +.
The electron transport chain connects the two photosystems and operates in the stroma lamellae.
Electrons in PS I are excited by blue light of wavelength 400 nm.
Correct Answer
Detailed Explanation
Non-cyclic photo-phosphorylation occurs when both PS II and PS I work in series, producing ATP and NADPH + H +. This is supported by the context that describes the sequential operation of the photosystems in the electron transport chain.
