Dark reactions make use of these organic energy molecules (ATP and NADPH). Thisreaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy while NADPH provides the electrons required to fix the CO2 (carbon dioxide) into carbohydrates.
Well the water molecules connect to the light molecules and then when that happens the water molecules cover the light and makes a dark reaction
