Passive and Active Transport - Amoeba Sisters #Shorts

What is a characteristic of passive transport?

• Requires ATP

• Moves substances against their concentration gradient

• Does not require ATP

• Only involves water movement

In passive transport, how do substances generally move?

• From low concentration to high concentration

• From high concentration to low concentration

• Only into the cell

• Only out of the cell

Which type of transport uses a protein to help substances move across the cell membrane but does not require energy?

• Active transport

• Endocytosis

• Facilitated diffusion

• Osmosis

What is true about active transport?

• It moves substances from high to low concentration.

• It does not require ATP.

• It moves substances against their concentration gradient.

• It only involves small molecules.
