Create a 3-dimensional model of a section of the cell membrane. (examples shown in class) This model should include all the proteins we discussed in class (non-gated, gated, carrier, pump, glycoproteins, etc…) as well as an example of an item that passes through that protein, if applicable. (i.e. sodium, alcohol, etc…) It should also include any other item in the cell membrane, such as cholesterol. You may make the model out of the material of your choosing (but not food items). You should create a separate key that denotes what each item on the model represents.
The table below shows the items you must include and what you will be graded on.
Due: Monday 3/1/10
| Parts | Diffusing Items | Overall Quality |
|---|---|---|
| phospholipid bilayer | O2, CO2, or alcohol | 3-D |
| non-gated channel/aquaporin | H2O | labeled properly (with separate key) |
| gated channel | Ion (ie. Na+) | construction quality & effort |
| carrier protein | glucose | |
| pump | Na/K | |
| glycoprotein/antigen | ||
| cholesterol |
