what are the usable substances (like batteries) produced by the light dependent reactions?
water and photons
atp and nadph
adp and nadp+
photosystems i and ii

Explanation:

In the Light - Dependent Reactions of photosynthesis, light energy is used to convert ADP to ATP (adenosine triphosphate) and NADP+ to NADPH (nicotinamide adenine dinucleotide phosphate). These molecules (ATP and NADPH) store energy and are used in the Light - Independent Reactions (Calvin Cycle) to synthesize glucose. Water is a reactant in the Light - Dependent Reactions (split to release oxygen), and photons are the source of light energy. ADP and NADP+ are the "spent" forms (they are reactants in the Light - Dependent Reactions to be converted to ATP and NADPH). Photosystems I and II are the protein - pigment complexes that capture light energy, not the energy - storing products.

Answer:

ATP and NADPH
