Question

correctly color code and identify the name for each part of the cell membrane.
letter name/color letter name/color
a phospholipid bilayer (no color) h peripheral protein (red)
b integral protein (pink) i cholesterol (blue)
f fatty acid tails (orange) c glycoprotein (green)
g phosphate heads (yellow) e glycolipids (purple)

match the cell membrane structure or its function with the correct letter from the cell membrane diagram.
letter structure/function letter structure/function
attracts water repels water
helps maintain flexibility of membrane make up the bilayer
involved in cell - to - cell recognition help transport certain materials across cell membrane

Explanation:

1. Attracts water: Phosphate heads (G) are hydrophilic and attract water.
2. Helps maintain flexibility of membrane: Cholesterol (I) helps maintain membrane flexibility.
3. Involved in cell - to - cell recognition: Glycoproteins (C) and glycolipids (E) are involved in cell - to - cell recognition.
4. Repels water: Fatty acid tails (F) are hydrophobic and repel water.
5. Make up the bilayer: Phospholipids (A, composed of phosphate heads and fatty acid tails) make up the bilayer.
6. Help transport certain materials across cell membrane: Integral proteins (B) help transport certain materials across the cell membrane.

Answer:

1. G
2. I
3. C, E
4. F
5. A
6. B
