B)noncyclic photophosphorylation
C)dark reactions
D)proton-motive photophosphorylation

Question

Quizplus · Accepted Answer

Noncyclic photophosphorylation is the process by which ATP is formed during oxygenic photosynthesis. This process involves the transfer of electrons from water to photosystem II, and then to photosystem I, before being used to generate ATP through the process of chemiosmosis. Cyclic photophosphorylation, on the other hand, only produces ATP and involves the transfer of electrons within photosystem I. Dark reactions, also known as the Calvin cycle, are not involved in the formation of ATP during photosynthesis. Finally, proton-motive photophosphorylation is a general term used to describe the process of ATP synthesis using energy derived from a proton gradient (e.g., in mitochondria or chloroplasts) and is not specific to photosynthesis.
