- A.
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
- C.
Photophosphorylation
- 3.During photosynthesis, what is pumped into the thylakoid space?

Sodium ions
- B.
Hydrogen ions
- C.
Potassium ions
- 4.What pumps the hydrogen ions into the thylakoid space?
- A.
A cytochrome complex
- B.
Hydrogen ion pumps
- C.
Nothing; they diffuse passively
