Ions cross the membrane through channels. What factors will affect the movement of the ions?
A) concentration gradients
B) electrical gradients
C) pressure gradients
D) chemical and electrical gradients

Question

Quizplus · Accepted Answer

Ion movement is affected by both the chemical concentration gradient and the electrical gradient that exists across the membrane (which is affected by the relative charges on either side of the membrane). Pressure gradients are not typically a major factor in ion movement.
