Sample analogy: socks : feet :: gloves : hands
Sample analogy: socks : feet :: gloves : hands
Explanation: The analogy above is read, "Socks are to feet as gloves are to hands." The analogy means that the two pairs have something in common, even though socks and gloves don't seem to be related at first glance. Socks keep feet warm, just as gloves keep hands warm.

Analogy 1: Swimming upstream : active transport : : floating downstream : passive transport
Analogy 1: Swimming upstream : active transport : : floating downstream : passive transport
Explanation: Swimming upstream means the swimmer uses energy, much like a cell uses energy to pump solutes in or out. Floating downstream is going with the current and does not require the swimmer to use any energy, much like water can diffuse into or out of a cell without the use of energy.

Analogy 2: Toll roads : active transport : : regular highways : passive transport
Analogy 2: Toll roads : active transport : : regular highways : passive transport
Explanation: You must pay to use the toll road just as a cell must "pay" with its energy, ATP, to use a protein pump. Both are faster, but "cost" more. You can drive on a regular highway, like Route 7, for free, but it takes longer to get where you are going.

Using the diagram above, tell which part(s) of the cell membrane are made of each macromolecule.

Phospholipids - make up the bilayer (two layers); the hydrophilic heads face the inside and outside of the cell where there is water, while the hydrophobic tails face inward to stay away from the water inside and outside the cell. Very small, nonpolar molecules can pass directly through. This is called diffusion, or simple diffusion.

Protein channels (also called channel proteins or transport proteins or transmembrane proteins) - allow "large or charged" substances to pass through the cell membrane, into or out of the cell. This can be active transport, such as protein pumps, or passive, such as osmosis or other types of facilitated diffusion.

Cholesterol - helps keep the cell membrane fluid and flexible. It's kind of like adding butter to cooked pasta; it keeps it from all sticking together into one big clump.

Sugar side chains (carbohydrate markers) - mark the outside of the cell to share information with other nearby cells. They are on our red blood cells and determine our blood types.
