1 Macromolecule stations 6 stations 1. Sugar and protein paper pieces to build (with waters) 2. Fatty acid and nucleic acid paper pieces to build with (and water) 3. DNA model with several pieces removed to build nucleotides 4. Glucose built molecule. 5. Lipid molecule and paper model. 6. Amino acid molecule and paper model.

2 Biology: Macromolecules Name: Station 1 1.) Assemble a disaccharide sugar. a. The building block/monomers of carbohydrates are. Place 2 of these into a chain and anywhere that 2 pieces touch, use the triangle water to point to the bond site (one water is always released from each bond site during dehydration synthesis.) disaccharide. 2.) Assemble the remaining monomers into a polysaccharide sugar. a. Place the remaining carbohydrate monomers into a chain and anywhere that 2 pieces touch, use the triangle water to point to the bond site. polysaccharide. 3.) Assemble a 4-monomer protein. a. The building block/monomers of proteins are. Place 4 of these into a chain and anywhere that 2 pieces touch, use the triangle water to point to the bond site 4- monomer protein. 4.) Assemble the remaining monomers into another protein. a. Place the remaining protein monomers into a chain and anywhere that 2 pieces touch, use the triangle water to point to the bond site. -monomer protein (place the correct number in the blank space).

3 STATION 2 5.) Assemble a triglyceride (common lipid). a. The building block/monomers of all lipids are. But to build a triglyceride you will need what additional piece? b. Look up triglycerides in your notes to find their shape: c. Assemble a triglyceride into the correct shape, and anywhere that 2 pieces touch use the triangle water to point to the bond site. d. Once you are sure you have a correct arrangement, draw it here and label it as a triglyceride. 6.) Assemble a DNA nucleotide. a. The building block/monomers of nucleic acids are. For DNA, this is made of a + +. b. Assemble the three components as shown by the diagram in your notes. Anywhere that 2 pieces touch, use the triangle water to point to the bond site. c. Once you are sure you have a correct arrangement, draw it here and label it as a DNA nucleotide. STATION 3 7.) What type of macromolecule is shown here? 8.) What is the monomer (base unit) of this type of macromolecule? 9.) Assemble a base unit (monomer) and draw it here. Label each of the 3 subunits that make up this monomer:

4 Station 4 10.) Use the dichotomous key (if necessary) to figure out what type of molecule. What type of macromolecule is show here? 11.) What are the black balls?, the white balls?, the red balls? 12.) Is this a monomer or a polymer? 13.) Place each item below under the correct heading: Station 5 14.) Use the key above to determine the type of macromolecule here: 15.) What are the extra three little molecules? 16.) How and why did the extra three little molecules form?. Station 6 17.) Name the monomer: 18.) What is the blue ball? 19.) When two monomers of this type of macromolecule join, what is the name given to the bond they form?. 20.) How many different types of this monomer are there?

5 Directions Complete the table by putting an X in the correct column for each description. (Only one box per question.) Description Lipids Nucleic Acids Proteins Carbohydrates Commonly called fats and oils Contain carbon, hydrogen, and nitrogen Contain peptide bonds DNA and RNA are examples Follow the general formula (CH 2 O) n Form skin, blood, hair, muscles Lactose and Cellulose are examples Made up of amino acids Made up of nucleotides Most consist of 3 fatty acids bonded to a glycerol Used for long-term energy storage
