  • 10

    What are the 2 types of F0F1-ATPase

    F, V

  • 11

    F0F1-ATPase and P-type ATPase generate what across the membrane?

    ABC transporters produce what gradients and has much wider solutes?

    Ion

  • 13

    What is F0F1-ATPase

    Is a protein using protons generated by other proteins to make ATP, it works both ways

  • 14

    Where is F0F1-ATPase located?

    In mitochondria, chloroplast, bacteria

  • 15

    What does V0V1-ATPase do

    Pumps protons into the cell

  • 16

    Where is V0V1-ATPase located at?

    In vacuoles

  • 17

    What does f1 do in f0f1?

    Make and break ATP

  • 18

    What does f0 do in f0f1?

    Allows protons to cross

  • 19

    Types of subunits in f0f1?

    A, b, y

  • 20

    Has ATP but doesn't help

  • 21

    What does b subunit do

    Has no ATP or ADP but helps
