The correct answer is: Sodium and potassium ions move by active transport, and glucose moves by facilitated diffusion.
Because sodium and potassium are moved through cell membrane against their concentration gradients, transport requires energy (ATP), so it is active. <span>Glucose is a polar molecule and because the plasma membrane is impermeable to polar molecules transport of this important nutrient is accomplished by carrier proteins. This process is called facilitated diffusion and it is passive transport (doesn’t require energy).</span>
Explanation:
Oxygen is a gas that your body needs to work properly. Your cells need oxygen to make energy. Your lungs absorb oxygen from the air you breathe. The oxygen enters your blood from your lungs and travels to your organs and body tissues
