Cell Transport

Which of the following is the BEST definition for passive transport?

• Movement of substances through a cell membrane from a high to low concentration without the use of energy

• Movement of substances through a cell membrane from a low to high concentration requiring the use of energy

• Movement of substances through a cell membrane from a low to high concentration without the use of energy

• Movement of substance through a cell membrane from a high to low concentration requiring the use of energy

Which of the following IS NOT an example of passive transport?

• Diffusion

• Facilitated Diffusion

• Osmosis

• Endocytosis

_____________ occurs when a substance is too large to flow through a cell membrane and it uses a protein "door".

• Diffusion

• Osmosis

• Exocytosis

• Facilitated Diffusion

Select the correct definition for "Osmosis":

• A molecule is too large to pass through a cell membrane and therefore uses a transport protein

• The movement of substances from a low to high concentration; cell energy is used

• The movement of water from a high to low concentration through a selectively permeable membrane

• The movement of substances from a high to low concentration

What is the main difference between passive and active transport?

• Passive transport requires energy; active transport does not require energy.

• Active transport requires energy; passive transport does not require energy.

• Both passive and active transport require energy

• Neither passive or active transport require energy.
