How do small ions like Na+ of K+ pass through the plasma membrane?
A)gated channels
B)ion channels
C)carrier proteins
D)simple diffusion

Question

Quizplus · Accepted Answer

Small ions like Na+ and K+ pass through the plasma membrane via ion channels, which are proteins that form pores in the membrane and allow ions to pass through via facilitated diffusion. This is a selective process, as different types of ion channels will only allow specific types of ions to pass through.
