Question

which protein complex splits water? photosystem ii chlorophyll photosystem i nadph

Explanation:

In the light - dependent reactions of photosynthesis, Photosystem II (PSII) is the protein complex that splits water. It uses light energy to oxidize water molecules, releasing oxygen as a by - product and generating electrons, protons for the electron transport chain and ATP synthesis. Chlorophyll is a pigment involved in light absorption, Photosystem I is involved in the later stages of the electron transport chain, and NADPH is an electron carrier produced in the light - reactions.

Answer:

Photosystem II
