  Energy given off by photolysis in the light-dependent reaction
- B.
  
  ATP
- C.
  
  Energy given off by an electron passing down the first electron transport chain in the light-dependent reaction
2.

Chemiosmosis allows the transformation of ADP into ATP. This process in photosynthesis is known as:
- A.
  
  Photolysis
- B.
  
  Phosphorylation
