How does light interact with the photosystems to excite the reaction center chlorophyll?
Light hits chlorophyll and will break down water to take an electron, this electron travels through chlorophyll molescules until it reaches the cholorophyll A molecule and will then become exited. This electron goes through chemiosmosis and the electron transport chain and oxidizes ADP+P and NADP+ forming ATP and NADPH that will be later used in dark reactions of photosynthesis.
