    Mitochondria and chloroplasts are the only two eukaryotic organelles with a double membrane.
    • A. 

      True

    • B. 

      False

  • 3. 
    The waste products of photosynthesis are important reactants in cell metabolism, and vice versa.
    • A. 

      True

    • B. 

      False

  • 4. 
    The internal membranes of both mitochondria and chloroplasts help increase surface area for reactions.
    • A. 

      True

    • B. 

      False

  • 5. 
    In both chloroplasts and mitochondria, the internal membranes are cross-linked by tube-like structures called lamellae.
    • A. 

      True

    • B. 

      False

  • 6. 
    Both photosynthesis and cell metabolism involve cascades and cycles.
    • A. 

      True

    • B. 

      False

  • 7. 
    Mitochondria are filled with a fluid called the stroma, and Chloroplasts have a similar fluid called the matrix.
    • A. 

      True

    • B. 

      False

  • 8. 
    The reactions that happen in the mitochondrial matrix are mainly redox reactions, with the goal of making NADH and FADH2 while regenerating oxaloacetate.
    • A. 

      True

    • B. 

      False

  • 9. 
    The chloroplast relies on pigment molecules, acting as enzymes, embedded in an internal membrane. They are arranged in clusters called photosystems, something like an electron transport chain might be.
    • A. 

      True

    • B. 

      False

  • 10. 
    The goal of the electron transport chain is to accumulate H+ ions in the intermembrane space, to keep ATP Synthase working.
    • A. 

      True

    • B. 

      False

  • 11. 
    The internal membranes of chloroplasts are called thylakoids, and those in the mitochondrion are called cristae.
    • A. 

      True

    • B. 

      False

  • 12. 
    The movement of electrons in the electron transport chain is in this order:  Cytochrome proteins, NADH dehydrogenase, Ubiquinone,
    • A. 

      True

    • B. 

      False

  • 13. 
    Neither photosynthesis nor electron transport would function without membrane-embedded proteins.
    • A. 

      True

    • B. 

      False

  • 14. 
    Both photosynthesis and cell metabolism rely on NADH as an electron carrier.
