Detailed explanation-1: -1: Photosystem I I: In the photosystem II (PSII) reaction center, energy from sunlight is used to extract electrons from water. The electrons travel through the chloroplast electron transport chain to photosystem I (PSI), which reduces NADP+ to NADPH.

Detailed explanation-2: -Here are the basic steps: Light absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. There, energy is transferred to P680, boosting an electron to a high energy level.

Detailed explanation-3: -Photosystem II is the first membrane protein complex in oxygenic photosynthetic organisms in nature. It produces atmospheric oxygen to catalyze the photo-oxidation of water by using light energy. It oxidizes two molecules of water into one molecule of molecular oxygen.

Detailed explanation-4: -First, the PSII light receptor molecules capture light and excite molecules. This process leads to photolysis, as water molecules are broken into hydrogen and oxygen. The oxygen is released and the hydrogen builds up within the thylakoid membrane.

Detailed explanation-5: -The first process of this process is to entrap light. This step occurs as light reactions that involve photophosphorylation reactions involving photosystems I and II. The entrapped light is used in the formation of energy such as ATP and NADH. This energy is used to process various biosynthesis reactions.
