• 3 Different colored Twizzlers

• 1 Sour Punch Straw

• 1 Rubber Band

• 50 toothpicks (attach one skittle to each end)

• 1 Large M&M (peanut or pretzel)

• 1 regular M & M

• Scissors

1. Gather the toothpicks into a bundle and place the rubber

band around the middle to keep them in a bundle.

2.Place a receptor molecule into the cell membrane.

• a. Take one of the twizzlers and place it through the bundle

• b.Bend one end of it into a circular shape. This shape represents how signal molecules bind to

specific molecules. Only a circular-shaped molecule can bind with this receptor.

3.Use the second twizzler as a carbohydrate chain. Place it in the bundle, just as in step 2. Don’t bend

this twizzler.

4.Cut your sour punch straw in half. Place each half into different locations in the bundle. These

represent the protein channels and pumps.

5.Holding the bundle vertically, place the large M&M on top of the bundle. Does it pass between the

toothpicks? Why or why not?

6.Place the large M&M on top of the sour punch straw. Does it pass through the straw? Why or why

not?

7.Still holding the bundle vertically, place the regular M&M on top of the bundle. Does it pass between

the bundle? Why or why not?

8.Place the regular M&M on top of the straw. Does it pass through the straw? Why or why not?

9.Place your mouth on the end of the bundle and blow. Can you feel air on the other side of the bundle?

Why or why not?

10.Explain how the bundle and straws actually represent the components of the a real cell membrane.

11.Roll the bundle between your hands. Do the individual toothpicks move? Without pulling the straw

out can you move it between the toothpicks? How does this represent the fluid mosaic model?

When you are done experimenting, enjoy your candy! ☺

Co2

a compound that reacts with an acid to form a salt

raises the ph. Level

Helps the body by allowing many kinds of molecules

to dissolve in the cells allowing many substances to

be transported

Helps the body by maintaining a constant temperature

Evaporation of water in perspiration cools the body

Water works as a lubricant to protect against damage

Bodies mainly made of, “cradle of life”

O2

a compound capable of neutralizing alkalis lowers

the ph. Balance

Formed by an acid and a base

Organic Molecules

• INRTO - Most living things are organic molecules, meaning that they

contain carbon. Most organic molecules are made of subunits called

monomers which together create a polymer. There are four major

organic molecules. Match their name to their definition below…

Carbohydrates

Lipids

Proteins

Nucleic Acids

Monosaccharide [simple sugar] or

the organic molecules composed of

monosaccharide’s bound together by

chemical bonds.

Substance composed principally of

carbon, oxygen, and hydrogen;

contains a lower ratio of oxygen to

carbon and is less polar than

carbohydrates; generally soluble in

nonpolar solvents

Macromolecule consisting of long

sequences of amino acids linked

together by peptide bonds.

Polymer of nucleotides, consisting of

DNA and RNA; forms a family of

substances that comprise the genetic

material of cells and control protein

synthesis.
