Question

In an experimental system in which ion pumps maintain steady concentration gradients of a resting cell: the Na* concentration is higher outside of the cell than inside the K+ concentration is higher inside the of cell than outside the Na* concentration gradient is larger than the K* concentration gradient the cell is equally permeable to Na* and K Based on these conditions, choose all of the following statements that are TRUE The resting membrane potential will be positive. The resting membrane potential will be negative. The equilibrium potential for Na will be negative. The equilibrium potential for K will be positive The equilibrium potential for Na* will be positive. The equilibrium potential for K+ will be negative.

Explanation / Answer

ANS) The correct options are:

The resting membrane potential will be positive.

The equilibrium potential for K+ will be positive.

The equilibrium potential for Na+ will be positive.

because A resting neuron has a voltage over its layer called as the resting membrane potential of it. Therefore, this resting potential is dictated by fixation slopes of particles over the layer and by film penetrability to each kind of ion it allows to penterate through its membrane.
In a resting neuron, Na+and K+. particles that have more penetration capabilities than any other ions move down their inclinations by means of channels, prompting a partition of charge that makes the resting potential so, that the resting potential is near the balance capability of K+ and has positive resting membrane potentials and equilibrium potentials.
