The probability that a single potassium channel is open is directly proportional to the driving force on the channel.

____________ channels do NOT have an inactivation domain.

For a neuron at rest, if you greatly reduced the permeability of potassium and increased the permeability for sodium, what would you expect as a result? (Select all that apply)

The voltage-gated sodium channel is mutated so that it de-inactivates more quickly than normal. How will the neuron be affected?

You voltage clamp a neuron at +30mV. Select the answer which best describes the driving force on sodium and potassium in this system. (Remember, assume Vrest = -60mV; EK+ = -70 mV; ENa+ = +50mV; T = 19°C; Threshold = -40mV)

If you voltage-clamp a neuron up to +60mV, what type of current(s) will be detected? (select all that apply)

At the resting state, a typical mammalian neuron is more __insert answer 1___ on the inside compared to the outside, with more __insert answer 2___ on the inside compared to the outside. answers choices are given as answer 1 comma answer 2

Which of the following statements is/are true regarding driving force? (select all that apply)

To have a current for ion X (IX) which of the following is/are required?

A cell has an extracellular chloride (Cl-) concentration of 100 mM and an intracellular chloride (Cl-) concentration of 10 mM. What is the equilibrium potential for chloride (Cl-) at 19 deg C?
