Term for formation of ATP using light energy in grana of chloroplast
A
Adenosine triphosphate
B
Photolysis
C
Respiration
D
Photophosphorylation
Explanation: 

Detailed explanation-1: -Photophosphorylation is the process of utilizing light energy from photosynthesis to convert ADP to ATP.

Detailed explanation-2: -C ATP Synthesis. ATP synthesis in chloroplasts is called photophosphorylation and is similar to oxidative phosphorylation in mitochondria.

Detailed explanation-3: -Photophosphorylation is the synthesis of ATP from ADP and inorganic phosphate (Pi) in the presence of light, inside chloroplast. Photophosphorylation is of two main types-cyclic and non-cyclic photophosphorylation.

Detailed explanation-4: -This process requires light to be absorbed twice, once in each photosystem, and it makes ATP . In fact, it’s called photophosphorylation because it involves using light energy (photo) to make ATP from ADP (phosphorylation).
