Which term best describes the movement of NH₄⁺ ions into a cell down an electrochemical gradient?

Question

Quizplus · Accepted Answer

Facilitated diffusion is the movement of ions or molecules across a plasma membrane from an area of high concentration to an area of low concentration, down their electrochemical gradients, with the aid of a transport protein. In this case, the movement of NH₄⁺ ions into the cell is down an electrochemical gradient, without the expenditure of energy, and with the aid of a transport protein, which fits the definition of facilitated diffusion.
