Using the space below, draw a model (picture, representation) of a cross-section
of a cell membrane, including and labeling the following elements:
a. Phospholipid bilayer, noting hydrophilic heads and hydrophobic tails
b. Cholesterol
c. Integral membrane proteins (include 1 glycoprotein and label the
carbohydrate)
d. Peripheral membrane proteins
Describe how integral membrane proteins and peripheral membrane proteins are
different in your own words, and include in your description what type of amino
acids you might find on these proteins.
A phospholipid that is destined to become part of the plasma membrane is synthesized inside a cell. Describe the process of making this molecule and its path to becoming part of the plasma membrane, giving specific details about where in the cell it would be for each step and each of the organelles/cell structures involved.
Each compartment of the endomembrane system of a cell is connected to the plasma membrane. Create a simple diagram of a cell including the RER, Golgi apparatus, vesicle, and the plasma membrane. Starting with the RER, use two different colors to represent the inner and outer halves of the bilayer for each of these membranes. What do you observe?
