The ease with which a cell membrane will permit ions to cross is referred to as
A)the concentration gradient.
B)permeability.
C)the action potential.
D)conductivity.

Question

Quizplus · Accepted Answer

Permeability refers to the ease with which molecules or ions can pass through a membrane. The higher the permeability, the easier it is for ions to cross the membrane. The concentration gradient refers to the difference in the concentration of ions between the inside and outside of the cell, which affects the movement of ions across the membrane, but is not a measure of how easy or difficult it is for them to do so. Action potential and conductivity are related to the electrical activity in cells, but are not measures of membrane permeability.
