    About the Lecture

    The lecture Active Transport: Sodium-potassium Atpase – Biological Membranes by Kevin Ahern, PhD is from the course Biochemistry: Basics.


    Included Quiz Questions

    1. The movement of molecules across the membrane against their concentration gradients by using energy
    2. The movement of sodium ions across the membrane along their concentration gradients by using energy
    3. The movement of sodium ions across the membrane against their concentration gradients without using any energy
    4. The movement of water molecules across the membrane against its concentration gradient by using the energy in the form of NADH2
    5. The movement of water molecules across the membrane along its concentration gradient by using the energy in the form of NADH2
    1. The Na+/K+ pump uses energy in the form of ATP to transport the Na+ and K+ ions along their concentration gradients
    2. The Na+/K+-ATPase pump is an electrogenic transmembrane enzyme present in the cell membrane of animal cells
    3. The Na+/K+ pump puts three Na+ ions out of the cell for every two K+ ions taken in
    4. The Na+ /K+ -ATPase pump maintains the resting potential across the cell membrane
    1. The cells will swell up and lyse due to higher osmolarity inside the cell
    2. The cell will show the phenomenon of plasmolysis
    3. The cell will keep on working as it does under normal conditions
    4. The cell will start to grow, and eventually it will divide into two cells
    5. The cell will start to synthesize heat shock proteins to cope with the high salt concentrations around the cell
