Which outcome occurs when cyclic electron flow predominates in a plant's thylakoid membranes?

💡 Explanation

When cyclic electron flow predominates, electrons cycle back to photosystem I, stimulating proton gradient formation, thereby increasing ATP production through chemiosmosis, because electrons do not pass through NADP+ reductase to generate NADPH. Therefore, increased ATP production results, rather than other outputs requiring both ATP and NADPH from non-cyclic electron flow.
