Question

5 multiple choice 1 point which of the following is an example of active transport? facilitated diffusion of glucose sodium - potassium pump simple diffusion of oxygen osmosis of water

Explanation:

Active transport requires energy to move substances against their concentration gradient. The sodium - potassium pump uses ATP to move sodium ions out of the cell and potassium ions into the cell against their concentration gradients. Facilitated diffusion, simple diffusion, and osmosis are passive transport processes that do not require energy input.

Answer:

B. Sodium - potassium pump
