    About the Lecture

    The lecture Ion Channel Blocker and Opener – Biological Membranes by Kevin Ahern, PhD is from the course Biochemistry: Basics.


    Included Quiz Questions

    1. They promote movement of ions across membranes
    2. They use triphosphate energy go move ions across membranes
    3. They help to build proton gradients
    4. They are not produced by living cells
    1. Valinomycin — an ion channel blocker produced by human cell to inhibit the movement of antibiotics across the cell membrane
    2. Saxitoxin — Na+ ion channel blocker in nerve cells
    3. Minoxidil — antihypertensive vasodilator medication
    4. Retigabine — anticonvulsant used in treatment for partial epilepsies
    5. 2,4-Dinitrophenol — a proton ionophore that dissipates the proton gradient across mitochondria membrane
    1. A proton ionophore that can shuttle protons across biological membranes and disrupt the proton gradient across them
    2. An ion channel blocker for the movement of sodium ions across the mitochondrial membranes
    3. A multiple ion channel blocker for the movement of various ions across the cell membrane, mitochondrial membranes and nuclear membranes
    4. An ion channel blocker for the movement of calcium ions across the nuclear membranes
    5. An ion channel opener for the movement of potassium ions across the cell membrane

    very good lecture. pretty well organized and instructive. He has a deep knowledge of the material making me to pay special attention to all his lectures.
