When a plant cell requires additional ATP but has a sufficient supply of NADPH, it shifts its electron flow. Which component is bypassed during this cyclic pathway?
Q1. When a plant cell requires additional ATP but has a sufficient supply of NADPH, it shifts its electron flow. Which component is bypassed during this cyclic pathway?
Answer: Photosystem II
Explanation: Cyclic flow only involves PS I to produce ATP; PS II and NADP reductase are bypassed as no NADPH is needed.
