Passive Transport Independent Practice

What is the term used to describe the mixture of a solute in a solvent?

• Dissolution

• Emulsion

• Solution

• Suspension

Which solution is considered hypertonic?

• The solution with higher solute concentration

• The solution with lower solute concentration

• The solutions with equal solute concentration

• The solution with higher solvent concentration

What is another term for equilibrium?

How is the cell membrane able to achieve homeostasis?

• The cell membrane is semi-permeable

• The cell membrane is fully permeable

• The cell membrane is not permeable

Which type of Passive Transport is being represented in this picture?

• Passive Diffusion
• Simple Diffusion
• Active Diffusion
• Facilitated Diffusion

Answer explanation

Facilitated diffusion is a Passive Transport process that uses a "helper" protein to move large, charged, or polar molecules across the cell membrane!

Simple and Facilitated diffusion are powered by an unequal concentration gradient of HIGH to LOW

• True
• False

Answer explanation

Passive transport required NO ENERGY.

Molecules move from high to low with the natural flow.

What type of solution is this cell submerged in, causing it to lose water?

• Hypertonic solution

• Hypotonic solution

• Isotonic solution

Answer explanation

Water moves from a hypotonic area to a hypertonic area.

Remember

Hypertonic =

high solute and low water

Hypotonic =

low solute and high water.

High to Low with the Natural Flow.

Osmosis is a type of passive transport and required no energy. Which type of substance is moving across the cell membrane using osmosis?

• Na (Sodium)

• Ca (Calcium

• H₂O (water)

• C₆H₁₂O₆ (glucose)

Which of the following is the same for all Passive Transport processes?

• Low to High concentrations

• High to Low concentrations

• Requires ATP energy

• Doesn't require ATP energy

Answer explanation

Osmosis, diffusion, and facilitated diffusion are all Passive transport processes.

Osmosis moves water only

Diffusion moves small nonpolar molecules only

Facilitated diffusion moves large, charged, or polar molecules with a protein helper

True or False: Transport proteins are the only proteins found in the cell membrane

• True

• False

Answer explanation

Proteins within the cells membrane help it interact with the external environment of the cell.
