Finally, what will be the effect on the membrane potential if K+ loan move out of the cell?a) K+ will bring the membrane potential to 0 (neutral) b) The membrane potential won't be significantly affected (non-polarizing) c) K+ leaving will make the inside of the cell more negative (hyperpolarizing) d) K+ will make the inside of the cell more positive (depolarizing)

What is the application of electrical application in Cell Membrane potential gradient?
A cell biologist is performing an experiment using the voltage clamp method in which they are allowed to change the voltage in the membrane potential. They are wanting to record potassium currents and notice that for a certain membrane potential range, the voltage clamp highlights that there is an inward current of potassium. Would these readings make sense?
At rest, a neuron has a lower concentration of sodium than the surrounding fluid. The neuron also has a higher concentration of potassium inside the cell. The sodium-potassium ion pump is used to maintain the neuron in the resting state. Which of the following statements is true? A. Remaining at rest requires the use of ATP. B. Remaining at rest requires an input of sodium. C. Remaining at rest requires the activation of cotransporters. D Remaining at rest requires decreased permeability of the membrane.
What happens to the membrane potential inside and outside of the cell when K+ channels are open?
