Reactants. Reactants are the substances that are needed for a chemical reaction to occur. Without reactants there are no products.

Answer: Chemical energy
Explanation: During light dependent reactions of photosynthesis, light is absorbed by chlorophyll and other light absorbing pigments. The light energy absorbed is conserved as ATP and NADPH. In light dependent reactions, the light energy is used to split water molecules into hydrogen ions and oxygen molecules and consequent production of ATP and NADPH. This reaction is called photolysis of water. The oxygen molecules is evolved while the hydrogen ions are transferred to NADP+ to produce NADPH. In light dependent reactions, ATP and NADPH are produced.
ATP and NADPH are forms of chemical energy which are usable in the cells. Therefore, light energy is converted into chemical energy in light dependent reactions of photosynthesis.
