it is the first phase. it is making NADPh and ATP.
Photosystem two produces O2, ATP, and NADP+
Photosystem II plays a role in absorbing light energy and initiating the process of photosynthesis by passing electrons through the electron transport chain. It also splits water molecules to release oxygen as a byproduct.
Photosystem I (PSI) plays a crucial role in the light reactions of photosynthesis by absorbing light energy and facilitating the conversion of that energy into chemical potential. It primarily focuses on the reduction of NADP+ to NADPH, which is essential for the Calvin cycle. PSI works in conjunction with photosystem II (PSII) and receives electrons from the electron transport chain, ultimately contributing to the formation of ATP and NADPH, the energy carriers used in the synthesis of glucose during the light-independent reactions.
Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II during the process of photolysis. These electrons are used to replace the ones lost by chlorophyll when it absorbs light energy, allowing the photosystem to continue absorbing light and generating ATP and NADPH for the Calvin cycle.
we call it calvin cycle. It is making glucose.

No. Photosystems I and II are where light-dependent reactions occur, while the Calvin Cycle is where light-independent reactions occur. Photosynthesis begins with Photosystem II, then Photosystem I, then the products from there go to the Calvin Cycle. (yes photosystem II comes before photosystem I)

Donating electrons to photosystem 2
Plastocyanin is a copper-containing protein that plays a crucial role in photosynthesis by shuttling electrons between photosystem II and photosystem I in the thylakoid membrane of chloroplasts. It helps in the transfer of electrons during the light-dependent reactions of photosynthesis.
