Cell Membrane Function

an area with a large amount of particles is

• low concentration
• high concentration
• diffusion
• osmosis

Simple diffusion is the movement of

• water from low to high concentration

• solutes from low to high concentration

• water from high to low concentration

• solutes from high to low concentration

Which is true about active transport?

• It requires energy

• it does not require energy

• It moves substances with the concentration gradient

• it moves material from high to low concentration

Which of the following is responsible for getting large or charged (polar) molecules across the cell membrane?

• E
• B
• C
• D

Where is the hydrophobic region of the cell membrane?

• E
• B
• C
• A 

If the dots represent solutes, like salt, what type of solution is the cell in? (Hint: water is leaving cell)

• Isotonic

• Hypertonic

• Hypotonic

• diffused

This process requires energy and is a process for removing large toxins and waste from the cell.

• exorcism

• exocytosis

• endocytosis

• endoplasmic reticulum

Small, non-polar molecules like CO₂ and O₂ and NO can pass directly through the cell membrane using what type of transport?

• Simple Diffusion

• Osmosis

• Facilitated Diffusion

• Endocytosis

If you place a saltwater fish in a freshwater environment, what will happen to the fish

• Its cells will swell due to active transport

• Its cells will shrink due to active transport

• Its cell will swell due to osmosis

• Its cell will shrink due to osmosis
