Question

Quizplus · Accepted Answer

Facilitated diffusion is a type of passive transport that requires a specific membrane protein to allow molecules to pass through the membrane. Glucose requires membrane proteins known as glucose transporters to cross the membrane from an area of high concentration to an area of low concentration. Oxygen, sodium, potassium, and water can all diffuse across the membrane without using a membrane protein in a process known as simple diffusion or osmosis.
