Cell Transport Quiz preparation

What is the best definition for diffusion?

• The movement of molecules from a low concentration to a high concentration.

• The movement of water to an area of higher solute concentration.

• The movement of solutes from a low concentration to high with the help of a pump.

• The movement of molecules from a high concentration to low concentration.

What is the best definition for osmosis?

• The movement of molecules from a low concentration to a high concentration.

• The movement of water to an area of higher solute concentration.

• The movement of solutes from a low concentration to high with the help of a pump.

• The movement of molecules from a high concentration to low concentration.

What is facilitated diffusion?

• The movement of molecules from a low concentration to a high concentration.

• The movement of water to an area of higher solute concentration.

• The movement of solutes from a high concentration to low, with the help of a protein channel.

• The movement of molecules from a high concentration to low concentration.

What is a concentration gradient?

• When the concentration of molecules are different across a space.

• When their is more energy on the inside of a cell

• When their is more energy on the outside of a cell

• When 2 different types of solutes exist across a space.

Passive transport occurs when..

• Materials move against the concentration gradient (Low to high)

• Materials move against the concentration gradient (high to low)

• Materials move with the concentration gradient (high to low)

• Materials move with the concentration gradient (Low to high)

Active transport occurs when..

• Materials move against the concentration gradient (Low to high)

• Materials move against the concentration gradient (high to low)

• Materials move with the concentration gradient (high to low)

• Materials move with the concentration gradient (Low to high)
