What protein pigment and area of the chloroplast gets its electrons excited by sunlight? What occurs in the stroma?

chlorophyll

The chlorophyll obtains its electrons from water (H2O), producing O2 as a by-product. During the electron-transport process, H+ is pumped across the thylakoid membrane, and the resulting electrochemical proton gradient drives the synthesis of ATP in the stroma.
