What characterizes repolarization, the second phase of the action potential? [equilibrium potential] Once the membrane depolarizes to a peak value of +30 mV, it repolarizes to its negative resting value of -70 mV. [3]
The plasma membrane was depolarized to a positive value at the peak of the first phase of the action potential. Thus, it must repolarize back to a negative value.

What event triggers the generation of an action potential? [equilibrium potential] The membrane potential must depolarize from the resting voltage of -70 mV to a threshold value of -55 mV. [3]
This is the minimum value required to open enough voltage-gated Na+ channels so that depolarization is irreversible.

What is the first change to occur in response to a threshold stimulus? [equilibrium potential] Voltage-gated Na+ channels change shape, and their activation gates open. [3]
The activation gates of voltage-gated Na+ channels open very rapidly in response to threshold stimuli. The activation gates of voltage-gated K+ channels are comparatively slow to open.

What type of conduction takes place in unmyelinated axons? [equilibrium potential] continuous conduction [3]
An action potential is conducted continuously along an unmyelinated axon from its initial segment to the axon terminals. The term continuous refers to the fact that the action potential is regenerated when voltage-gated Na+ channels open in every consecutive segment of the axon, not at nodes of Ranvier.

An action potential is self-regenerating because __________. [equilibrium potential] depolarizing currents established by the influx of Na+ flow down the axon and trigger an action potential at the next segment [3]
The Na+ diffusing into the axon during the first phase of the action potential creates a depolarizing current that brings the next segment, or node, of the axon to threshold.

Why does regeneration of the action potential occur in one direction, rather than in two directions? [equilibrium potential] The inactivation gates of voltage-gated Na+ channels close in the node, or segment, that has just fired an action potential. [3]
At the peak of the depolarization phase of the action potential, the inactivation gates close. Thus, the voltage-gated Na+ channels become absolutely refractory to another depolarizing stimulus.

What is the function of the myelin sheath? [equilibrium potential] The myelin sheath increases the speed of action potential conduction from the initial segment to the axon terminals. [3]
The myelin sheath increases the velocity of conduction by two mechanisms. First, myelin insulates the axon, reducing the loss of depolarizing current across the plasma membrane. Second, the myelin insulation allows the voltage across the membrane to change much faster. Because of these two mechanisms, regeneration only needs to happen at the widely spaced nodes of Ranvier, so the action potential appears to jump.

What changes occur to voltage-gated Na+ and K+ channels at the peak of depolarization? [equilibrium potential] Inactivation gates of voltage-gated Na+ channels close, while activation gates of voltage-gated K+ channels open. [3]
Closing of voltage-gated channels is time dependent. Typically, the inactivation gates of voltage-gated Na+ channels close about a millisecond after the activation gates open. At the same time, the activation gates of voltage-gated K+ channels open.

In which type of axon will velocity of action potential conduction be the fastest? [equilibrium potential] Myelinated axons with the largest diameter [3]
The large diameter facilitates the flow of depolarizing current through the cytoplasm. The myelin sheath insulates the axons and prevents current from leaking across the plasma membrane.

On average, the resting membrane potential is -70 mV. What does the sign and magnitude of this value tell you? [equilibrium potential] The inside surface of the plasma is much more negatively charged than the outside surface. [3]
The inside surface of the plasma membrane accumulates more negative charge because of the presence of Na+ and K+ gradients and the selective permeability of the membrane to Na+ and K+.

The plasma membrane is much more permeable to K+ than to Na+. Why? [equilibrium potential] There are many more K+ leak channels than Na+ leak channels in the plasma membrane. [3]
More leak channels translates into more leakiness. Thus the outward flux of K+ is greater than the inward flux of Na+.

The resting membrane potential depends on two factors that influence the magnitude and direction of Na+ and K+ diffusion across the plasma membrane. Identify these two factors. [equilibrium potential] The presence of concentration gradients and leak channels [3]
The concentration gradient and the large number of K+ leak channels allow for rather robust K+ diffusion out of a cell. In contrast, the concentration gradient and the relatively few Na+ leak channels allow for much less Na+ diffusion into a cell.

What prevents the Na+ and K+ gradients from dissipating? [equilibrium potential] Na+-K+ ATPase [3]
Also known as the Na+-K+ pump, or simply the pump, this transporter moves three Na+ out of the cell and two K+ into the cell for every ATP it hydrolyzes. This pumping action prevents the Na+ and K+ gradients from running down as these ions passively move through leak channels.
