Decreasing the extracellular concentration of K+ affects the resting
membrane potential by causing
a. hyperpolarization.
b. depolarization.
c. no change.
The difference between the electrical potential in the intracellular and extracellular cellular matrices when it is not excited is defined as the membrane potential. Each cell in the body has its own membrane capacity, but it can only be transformed and generating to an action potential by exciting cells like nerve cells and muscles.
The efflux of the K+(a cation) by K+ channels or the influx of the Cl– (anion) by the Cl– channels causes hyperpolarisation. The improvement in the membrane potency of a cell is hyperpolarization, which makes it more adverse. It prevents action potential by increasing the stimulus needed to move the membrane potential to the threshold for attaining the action potential.
Thus, option 'a' is the correct answer.
