The process of photophosphorylation takes place in:

Explanation

Option B is correct.The process of photophosphorylation takes place in the chloroplast. Photophosphorylation is the process by which light energy is used to produce ATP, the energy currency of the cell. It is the light-dependent reaction of photosynthesis. Photophosphorylation takes place in the thylakoid membranes of the chloroplast. The thylakoid membranes are stacked sacs that contain chlorophyll, the light-absorbing pigment. When sunlight hits the chlorophyll, it excites the electrons in the chlorophyll molecules. These excited electrons are then passed through a series of electron carriers, which eventually leads to the production of ATP. The ATP that is produced by photophosphorylation is used to drive the Calvin cycle, the light-independent reaction of photosynthesis. The Calvin cycle uses ATP to convert carbon dioxide into sugar.The other options are not organelles where photophosphorylation takes place:The nucleolus is a small structure within the nucleus that is involved in the production of ribosomes.The nucleus is the control center of the cell and contains the cell's DNA.The Golgi apparatus is involved in the packaging and processing of proteins and lipid
