The cell membrane is made of a phospholipid bilayer. Label its three parts: 1) charged phosphate group or head, 2) glycerol, and 3) the two fatty acid chains or tails. Mark the end that is polar (likes water) and the end that is nonpolar (doesn't like water). This is all review from Chapter 2.

List the function of each of the main three molecules that are found in the cell membrane.

Some molecules can cross the membrane while others cannot. What term describes this property: __(type the name of the term on the figure below)

A concentration gradient means there is a difference in the concentration of a substance in one location compared to another location.

Describe what is meant by a molecule moving down a concentration gradient.

The higher the concentration of dissolved particles in a solution, means that the concentration of water molecules in that solution is _______________.

Facilitated diffusion differs from simple diffusion because it requires a transport protein to move it across the membrane.

In facilitated diffusion, do molecules move down a concentration gradient or against a concentration gradient?

Use Figure above

Use Figure above

Experiment A. There was no change in the level of water in the visking tube or beaker after a 24 hour period, because the glucose concentrations inside and outside the visking tubing were the same.

Experiment B. Water moved out of the visking tube into the beaker, so the water level in the beaker rose higher and the water level in the glass tubing went down.

You become so dehydrated on a hot summer day that you go into shock and are taken to an emergency room at a hospital. They start you on an IV of saline solution to get you rehydrated. Why can't they give you an IV with just water in it?
