Question

What would be the effect of the opening of potassium channels on the function of neuron?

• A. It will continue to function normally
• B. It will function inconsistently
• C. It will no longer function due to sodium leakage
• D. It will continue to function but not transmit any impulses
• E. It will no longer function due to an overly positive charge

Answer 1

The correct option is A It will continue to function normally

Potassium channels are the non-gated always open passive ion channels that permit the diffusion of potassium ions out of the neuron down the concentration gradient and make the extracellular fluid outside the cell more positive as compared to cell's interior. This generates resting potential and allows normal functioning of the neuron. Thus, the correct answer is option A.
