What are all the ractants and products of the light reaction

The reactants are oxygen,carbon dioxide ,ATP, NADPH,chlorophyll and water

The products are GA3P, oxygen and water

Explanation:

The reactants of photosynthesis are oxygen, carbon dioxide, ATP , NADPH , chlorophyll and water. The products are GA3P , oxygen, glucose (sugar) and water. The necessary sources of photosynthesis are sun's energy, water and carbon dioxide.  

In the initial reactions water is used and oxygen is released. During the process the energy from sunlight is converted in to small amount of ATP.  The energy is called NADPH.  

Calvin Cycle: Together with carbon dioxide , the energy carrier are used to make glucose (sugar) through a process is known as Calvin Cycle.  

The waste product released by the light reaction is oxygen.  

it means there are 3 atoms of oxygen
