Detailed explanation-1: -That energy is relayed to the PSI reaction center (called P700). P700 is oxidized and sends a high-energy electron to NADP+ to form NADPH. Thus, PSII captures the energy to create proton gradients to make ATP, and PSI captures the energy to reduce NADP+ into NADPH.
Detailed explanation-2: -The reaction-center chlorophyll of photosystem I is known as P700 because. there are 700 chlorophyll molecules in the center.
Detailed explanation-3: -Electrons are transferred sequentially between the two photosystems, with photosystem I acting to generate NADPH and photosystem II acting to generate ATP.
Detailed explanation-4: -4. ATP is the product of photosystem I. 5. ATP and NADPH are two types of protein carriers.
Detailed explanation-5: -Both photosystems contain many pigments that help collect light energy, as well as a special pair of chlorophyll molecules found at the core (reaction center) of the photosystem. The special pair of photosystem I is called P700, while the special pair of photosystem II is called P680.
