Quiz zum Vortrag
Which of the following is true of ionophores?
- They promote the movement of ions across membranes.
- They use triphosphate energy to move ions across membranes.
- They help to build proton gradients.
- They are not produced by living cells.
- They are lipophobic substances.
Which of the following is NOT associated correctly?
- Valinomycin — an ion channel blocker produced by a human cell to inhibit the movement of antibiotics across the cell membrane
- Saxitoxin — Na+ ion channel blocker in nerve cells
- Minoxidil — antihypertensive vasodilator medication
- Retigabine — anticonvulsant
- 2,4-Dinitrophenol — a proton ionophore that dissipates the proton gradient across mitochondria membrane
Which of the following is true of 2,4-DNP?
- It is a proton ionophore that can shuttle protons across biological membranes and disrupt the proton gradient across the membrane.
- It is a sodium channel blocker located in the mitochondrial membrane.
- It is a multiple ion channel blocker that allows the movement of various ions across the cell, mitochondrial, and nuclear membranes.
- It is an ion channel blocker that allows the movement of calcium ions across the nuclear membrane.
- It is an ion channel opener that allows the movement of potassium ions across the cell membrane.
