Joseph Bienaim Caventou and Pierre Joseph Pelletier first isolated and named the molecule in 1817. Generally, On the walls of the mesophyll, the chloroplasts align along. NADPH plays a big role in the light-independent reaction when it is used, along with ATP, to produce high energy sugars. When both wavelengths are used, electrons can pass from photosystem II to photosystem I generating more ATP. Mitochondria produce energy, which is used to convert food into energy, whereas photosynthesis produces energy, which is used to power the cell. It is performed by a specialized intracellular organelle, the chloroplast, in plants and algae, which evolved much later. The two main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy. Resources.
