1. Which of the following is NOT a type of passive transport?
Facilitated diffusion
Osmosis
Active transport
Simple diffusion
2. The primary function of the sodium-potassium pump is to:
Facilitate water movement across the membrane
Pump sodium ions into the cell and potassium ions out of the cell
Maintain the resting membrane potential
Produce ATP for cellular energy
3. The movement of molecules from an area of high concentration to an area of low concentration is called .
4. is the movement of water across a selectively permeable membrane.
5. Active transport requires energy, typically in the form of , to move substances against their concentration gradient.
