During the light reaction of photosynthesis, which of the following phenomena are observed during cyclic phosphorylation as well as noncyclic phosphorylation?

Explanation

During the light reactions of photosynthesis, excitation of electrons by light and production of ATP occur in both cyclic and non-cyclic phosphorylation. Splitting of water and formation of NADPH occur only in non-cyclic phosphorylation. Cyclic phosphorylation recycles electrons within photosystem I and does not produce NADPH or oxygen.
