ATER VIEWING FIGURE 3.2
Phospholipid bilayer drawing:
2. Name the light blue/green structure of the cell and name
the molecule with a “heads” and “tails” that makes up this
structure.

3. Refer to page 38, Figure 2.11(c). Diagram a small
portion of the membrane showing 3 individual
phospholipid molecules. Label the following parts
of the membrane.
•
•
•
•
•
•
The polar heads of the phospholipids.
The nonpolar tails of the phospholipids.
The saturated fatty acid.
The unsaturated fatty acid.
The hydrophilic region of the membrane.
The hydrophobic region of the membrane.
Why is the “head” polar?
What chemical subgroup causes the
polar region? (Hint: See the green circle)
AFTER READING PAGE 50 TITLED “THE PLASMA MEMBRANE”:
4. Name the two types of proteins found in the membrane and explain their difference.
5. Most plasma membrane proteins are glycol proteins. How are they different than regular
proteins?
6. Draw an arrow to and label
the following structures:
• Phospholipid bilayer
• Polar head
• Non polar fatty acids
• Integral protein
• Peripheral protein
• Cholesterol molecules
7. Name the types of materials that will and will not pass through the plasma membrane.
Will pass through membrane
Will not pass through the membrane
8. Give the functions for the following proteins found in the plasma membrane:
PLASMA MEMBRANE
PROTEIN
ION CHANNEL
TRANSPORTER
ENZYMES
CELL IDENTITY MARKER
INTEGRAL OR
PERIPHERAL
FUNCTION
