Cell membrane coloring sheet
Please color a few of the nonpolar & hydrophobic phospholipid fatty acid tails dark green.
Color a few of the polar & hydrophilic phospholipid phosphate head groups red.
Color nonpolar & hydrophobic cholesterol yellow. This molecule prevents cell membranes from
becoming too fluid when temperatures are high.
Color an integral membrane carrier protein orange (you can’t tell from the drawing whether the
carrier protein is a passive transport channel or pore or whether it is an active transport pump).
Color a glycoprotein with an attached carbohydrate chain dark blue. This membrane protein and
its external sugar chain serves as a recognition protein, also known as a cell identification marker.
Color a peripheral membrane protein (on cytoplasmic side) purple. This peripheral protein allows
the cell to change organization of the cytoskeleton in response to messages from other cells.
Color light blue a receptor protein that is bound to a pentagon shaped hormone. This protein
allows the cell to receive messages from other cells which produce the hormone. Color the
hexagon shaped hormone pink.
Neatly draw an arrow to each of the colored structures and label them.
