Quizplus · Accepted Answer

Photosystem I and Complex I are not analogous as they have different functions and locations in photosynthesis and respiration respectively. Photosystem I is responsible for generating ATP and reducing NADP+ during photosynthesis while Complex I is responsible for oxidizing NADH and generating a proton gradient in the mitochondrial electron transport chain.
