When plants convert the light energy into chemical energy is called photosynthesis. The main component in this process is the chlorophyll pigment. It drives the synthesis of organic molecules in chloroplasts and is the one that absorbs light energy. The two stages of the photosynthesis process are the photo part (light reactions) and the synthesis ( Calvin cycle).
The Calvin cycle with ATP ( adenosine triphosphate) and NADPH (reduced form of Nicotinamide adenine dinucleo phosphate) is supplied by the light reactions of photosynthesis. The chemical factories of the plant are chloroplasts. The sun power for them. The light energy into the chemical energy of ATP and NADPH is transformed by the thylakoids present in chloroplasts. To supply the Calvin cycle with energy and reducing power to synthesize carbohydrates, this conversion occurs during the light reactions of photosynthesis.
Hence, ATP and NADPH is the correct answer.
