Cell Membrane Review

___________ form the two layers of the cell membrane. 

• Carbohydrates 

• Proteins 

• Phospholipids 

• Cholesterol

What does "bilayer" mean?

• one layer

• two layers

• laminated

• bilateral

Hydrophilic portion of cell membrane?

• A

• C

• D

• E 

What is structure A?

• carbohydrate chain

• phospholipid head

• phospholipid tail

• cholesterol

What is structure C?

• carbohydrate chain

• phospholipid head

• transport protein

• cholesterol

What type of transport is this?

• facilitated diffusion

• active transport

• diffusion

• osmosis

The cell below is in a _________ solution.

• Hypotonic

• Hypertonic

• Isotonic

A cell will __________________ in a hypotonic solution.

• swell and perhaps burst (lyse)

• shrink

• the size of the cell will not change

• the size of the cell will change from large to small and from small to large

This process moves nonpolar molecules, like oxygen and carbon dioxide, across the membrane through the bilayer.

• Diffusion

• Facilitated Diffusion

• Osmosis

• Active Transport

This process moves polar molecules, across the membrane through a protein.

• Diffusion

• Facilitated Diffusion

• Osmosis

• Active Transport
