Which one of the following manipulations will immediately depolarize the resting membrane potential of a typical neuron? A. opening of K+ channels B. an increase in extracellular K+ concentration C. exposure to a toxin that blocks the opening of voltage-gated Na+ channels D. exposure to a toxin that blocks the opening of voltage-gated K+ channels

Step 1
Step 1: The resting membrane potential of a typical neuron is around -70mV, which is maintained by the unequal distribution of ions across the cell membrane, with more K+ ions inside the cell and more Na+ ions outside the cell. Show more…

A typical action potential in a neuron is caused by which one of the following processes? a: a surge in the activity of the Na+/K+ pump b: a large increase in the intracellular concentration of K+ ions c: a large increase in the intracellular concentration of Na+ ions d: a brief increase in Na+ permeability followed by a brief increase in K+ permeability e: a simultaneous increase in the permeability of the membrane to both Na+ and K+ ions e

Which of the following actions allows for repolarization of a neuron? The opening of sodium channels, allowing to enter the neuron The opening of potassium channels, allowing potassium to leave the neuron The closing of both sodium and potassium channels to restrict movement of ions into and out of the neuron The inhibition of sodium and potassium pumps, stopping all ion movement into the neuron
