Passive Transport

In diffusion, molecules move until they reach:

• The mitochondria

• Equilibrium

• A higher concentration

• A solid state

What is osmosis?

• The movement of solutes from high to low concentration

• The movement of water across a selectively permeable membrane

• The movement of molecules requiring energy

• The transport of large particles into a cell

Filtration depends on which type of pressure?

• Osmotic pressure

• Hydrostatic pressure

• Atmospheric pressure

• Kinetic pressure

Facilitated diffusion requires which of the following?

• ATP energy

• Carrier or channel proteins

• Ribosomes

• Vesicles

After eating salty foods, you feel very thirsty.

 Which type of passive transport is responsible for this? 

• Osmosis

• Diffusion

• Filtration

• Facilitated diffusion
