elena-s [515]

Answer: NADPH and ATP

Explanation:

The mechanism of photosynthesis can be divided into two phases, light reaction, and carbon fixation. During the light reaction, photosynthetic pigments absorb radiant energy and undergo a series of photochemical reactions and convert the trapped energy into chemical energy which is stored in the form of NADPH and ATP. These two compounds constitute the assimilatory power. Light reaction is light dependent and it takes place in the grana of the chloroplast.
