Answer:
What is true of the light reaction of photosynthesis is that it produces ATP.
Step-by-step explanation:
Photosynthesis is the conversion of inorganic matter to organic matter thanks to the energy provided by light. In this process the light energy is transformed into stable chemical energy, being the NADPH (nicotine adenine dinucleotide phosphate) and ATP (adenosine triphosphate) the first molecules in which this chemical energy is stored. Subsequently, the reducing power of NADPH and the energy potential of the phosphate group of ATP are used for the synthesis of carbohydrates from the reduction of carbon dioxide.
