Which statement best describes photophosphorylation
a: it is the conversion of light energy to chemical energy
b: it is the flow of hydrogen ions down a concentration gradient
c: it is the process by which light energy
it is the addition of a phosphate group to adp to form atp using light energy absorbed during photosynthesis

c

Explanation:

"In the process of photosynthesis, the phosphorylation of ADP to form ATP using the energy of sunlight is called photophosphorylation."

d. It is the addition of a phosphate group to ADP to form ATP using light energy absorbed during photosynthesis.

format change of dna.  

because the light is a great source of energy for the plants to survive. (i hope this )
