In passive transport, molecules move from an area of __________ concentration to an area of __________ concentration.

Back

In passive transport, molecules move from an area of high concentration to an area of low concentration.

Front

What is the main difference between active transport and passive transport?

Back

Active transport requires energy (ATP), while passive transport does not.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of transporting molecules across a membrane via protein channels without energy.

Front

What role do protein pumps play in cellular transport?

Back

Protein pumps actively transport ions or molecules against their concentration gradient using ATP.
