When a chloroplast is deficient in NADP+ and shifts to cyclic photophosphorylation, what is the primary energetic product generated by the process?
Q1. When a chloroplast is deficient in NADP+ and shifts to cyclic photophosphorylation, what is the primary energetic product generated by the process?
Answer: ATP only
Explanation: Cyclic flow only produces ATP to meet high energy demands; NADPH is only produced during non-cyclic photophosphorylation via Photosystem I.
