Na⁺ and K⁺ both use ________ to passively diffuse across the plasma membrane.

Question

Quizplus · Accepted Answer

Na+ and K+ both use leak channels to passively diffuse across the plasma membrane. Leak channels are always open and allow ions to move down their concentration gradient without the need for energy. Facilitated diffusion uses carrier proteins to transport molecules or ions down the concentration gradient, while exocytosis is a process in which materials are transported out of the cell. Voltage-gated channels open and close in response to changes in the membrane potential, allowing ions to move across the membrane.
