  2. 2. CELL MEMBRANE EXPERIMENT • 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 rubberband 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 bendthis twizzler.4.Cut your sour punch straw in half. Place each half into different locations in the bundle. Theserepresent the protein channels and pumps.5.Holding the bundle vertically, place the large M&M on top of the bundle. Does it pass between thetoothpicks? 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 whynot?7.Still holding the bundle vertically, place the regular M&M on top of the bundle. Does it pass betweenthe 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 strawout can you move it between the toothpicks? How does this represent the fluid mosaic model?When you are done experimenting, enjoy your candy! ☺

  4. 4. 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… Substance composed principally of carbon, oxygen, and hydrogen; Carbohydrates contains a lower ratio of oxygen to carbon and is less polar than carbohydrates; generally soluble in nonpolar solvents Lipids Macromolecule consisting of long sequences of amino acids linked together by peptide bonds. Proteins Polymer of nucleotides, consisting of DNA and RNA; forms a family of substances that comprise the genetic material of cells and control protein synthesis. Nucleic Acids Monosaccharide [simple sugar] or the organic molecules composed of monosaccharide’s bound together by chemical bonds.Works Cited - Mcgraw-Hill, .Anatomy and Physiology.Essential Study Partner version 2.0.
