Active and Passive Transport Review

Which of the following is not a type of passive transport?

• Osmosis
• Diffusion
• Endocytosis
• Facilitated Diffusion

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)

• Active uses ATP (energy) and passive does not need energy

• Active stores transport proteins and passive releases

• Active uses hormones and passive does not

What is equilibrium?

• When concentrations cannot be balanced between two substances 
• When concentrations are balanced between two substances 
• Making the energy in the top half of your body equal the the energy in the bottom half
• Concentrations do not exist

Which picture shows the process of endocytosis?

• 
• 
• 
• 

Under what conditions will water flow into cells causing them to swell?

• When the solute concentration is higher inside the cell than outside.

• When solute concentration is higher outside the cell than inside.

• When the solution outside the cell is salty.

• When the cell is in an isotonic solution.

What happens to the cell membrane during exocytosis?

• Molecules pass directly through the phospholipids

• A vesicle fuses with the membrane and releases its contents out of the cell.

• Molecules use a transport protein to enter the cell.

• Water flows towards the higher solute concentration side of the membrane.

What type of movement is passive and the molecule needs the helps of a membrane protein to move through the cell membrane?

• Facilitated diffusion

• Simple diffusion

• Exocytosis

• Osmosis

Why do cells change in size and shape in different concentration solutions?

• The cells are consuming energy.

• The cells are absorbing nutrients from the solution.

• Water is entering or leaving the cells.

• The cells are undergoing mitosis.
