A brief quiz over chemiosmosis.


Questions and Answers
  • 1. 
    From what specifically is chemiosmosis fueled?
    • 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?
    • A. 

      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

  • 5. 
    Once the concentration of hydrogen ions in the thylakoid space is high enough, the ions diffuse passively through _________________ located on the thylakoid membrane, providing the energy needed to phosphorylate ADP into ATP.
    • A. 

      Cytochrome complexes

    • B. 

      Hydrogen ion channels

    • C. 

      ATP synthase channels

  • 6. 
    Chemiosmosis occurs where?
    • A. 

      In photosystem I

    • B. 

      In photosystem II

    • C. 

      Between photosystem II and photosystem I
