Explanation:
The diagram illustrates that the light-dependent phase of photosynthesis occurs in the lamellae of the chloroplasts while the light-independent phase occurs in the stroma. The light-dependent phase involves the use of light energy to split a water molecule. The high-energy electrons from the photolysis process are passed down a chain of proteins that harness the energy to make ATPs by photophosphorylation. NADPHs are also made.
The dark stage is the Calvin cycle. Carbon dioxide is reduced to glucose and because this is an anabolic process, then the ATPs made in the light stage are used in this cycle. The NADPHs, on the other hand, are used to reduce the carbon dioxide taken up by the plant into glucose.
