Question

which type of photophosphorylation typically provides the greatest energy payoff?
chemiosmosis
non - cyclic photophosphorylation
basic photophosphorylation
cyclic photophosphorylation

Explanation:

Non - cyclic photophosphorylation produces both ATP and NADPH, which are energy - rich molecules. Cyclic photophosphorylation only produces ATP. Chemiosmosis is a process involved in both but not a type of photophosphorylation. 'Basic photophosphorylation' is not a standard term. Non - cyclic photophosphorylation has a greater energy payoff as it generates more energy - carrying molecules for the Calvin cycle in photosynthesis.

Answer:

non - cyclic photophosphorylation
