Answer :
light excites the electron in the electron transport train and once it goes down the train water replaces the missing electron. the electron transport chain brings it down, hydrogen gets pumped across then when it slides back down the other side, energy is created. chlorophyll is the goo stuff that lets it absorb the light. carbon dioxide goes into the calvin cycle and it rearranged uses energy from the first part. the products of this part is sugar (C6H12O6) and oxygen.
water and carbon dioxide go in, oxygen and sugar come out
