The site for light reaction is
Open in App
Solution
The correct option is A Grana
During the light reaction stage of photosynthesis, light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP. In these reactions then the energy from sunlight is absorbed by the chloroplast. Grana are stacks of structures called thylakoids, which are little disks of the membrane on which the light-dependent reactions of photosynthesis take place. Grana is the site for light reaction. So, the correct option is A.
