Examine the illustration below; which statement best summarizes the contribution of Photosystem I (PSI)during photosynthesis? A)PSI provides the initial energy boost to the electrons on their way to Photosystem II (PSI I). B)PSI generates the excited electrons that initially accumulate within the thylakoid space and eventually drive ATP synthesis. C)PSI generates the high-energy electrons that are transported by NADPH to the Calvin cycle and will eventually reduce the carbon in CO₂. D)By cycling between reduced and oxidized states, PSI regulates the transmembrane passage of protons between the stroma and the thylakoid space.
