Botany - Photosynthesis in Higher Plants Question with Solution | TestHub

The light reaction of photosynthesis involves the use of direct sunlight and takes place inside the grana of the chloroplast. In the series of this reaction ATP and${\mathrm{N}\mathrm{A}\mathrm{D}\mathrm{P}\mathrm{H}}_2$are generated and are called the assimilatory power. Photolysis of water takes place during this reaction with the evolution of oxygen. They are so-called because during the dark reaction of photosynthesis they are used to provide the energy required for${\mathrm{C}\mathrm{O}}_2$assimilation.
