Active and Passive Transport

What is the main difference between active and passive transport?

• Active transport requires energy, while passive transport does not.

• Active transport moves molecules from high to low concentration, while passive transport moves them from low to high.

• Active transport involves osmosis, while passive transport involves protein pumps.

• Active transport is faster than passive transport.

Which of the following is an example of active transport?

• A) Diffusion

• B) Osmosis

• C) Protein pumps

• D) Facilitated diffusion

Which of the following is a passive transport mechanism?
