Carbohydrates Lipids Proteins Anything Goes in Biochemistry Enzymes 100 100 100 100 100 200 200 200 200 200 300 300 300 300 300 400 400 400 400 400 500 500 500 500 500 What are the elements and ratio of the elements that make up carbohydrates? What are carbon, hydrogen, and oxygen 1:2:1 ratio? Carbohydrates 100 The monomers of carbohydrates— What are monosaccharides? Carbohydrates 200 Which carbohydrate is not matched correctly with its function? (And give the correct function) A. Starch: stored energy for plants B. Glycogen: makes up exoskeleton of arthropods C. Cellulose: structural component of cell walls D. Glucose: quick source of energy for cells What is Glycogen: stored energy in muscle cells Carbohydrates 300 The characteristics listed below can be used to describe some molecules. 1. 2. 3. 4. inorganic supplies energy and fiber component of plant cell walls made of nucleotides Which two characteristics describe carbohydrates? What are supplies energy and fiber and component of plant cell walls? Carbohydrates 400 Daily Double In the lab, we preformed a chemical test by adding Benedicts Reagent to a food and heating it for about 5 minutes. What does the orange color indicate in the test tube on the left? What is Benedicts tests for the presence of glucose; the orange color is a positive test for glucose? Carbohydrates 500 DAILY DOUBLE In the lab, we preformed a chemical test by adding Benedicts Reagent to a food and heating it for about 5 minutes. What does the orange color indicate in the test tube on the left? What is Benedicts tests for the presence of glucose; the orange color is a positive test for glucose? Carbohydrates 500 Lipids are hydrophobic. This means that when they are added to water – What is they do not mix or separate? Lipids 100 The monomers of Lipids What are glycerol and fatty acids? Lipids 200 Which lipid is not matched correctly with its function? (You must give the correct function.) A. Fat: insulation and long term energy storage B. Waxes: covering and protection C. Phospholipids: major component of biological membranes D. Steroids: catalysts in chemical reactions What are steroids because they are cholesterol & sex hormones Lipids 300 Which structural diagram is an example of a saturated fatty acid? A B C What is molecule “B” ? Lipids 400 Give 2 similarities between carbohydrates and lipids. What are they both store energy and both use the elements Carbon, Hydrogen, and Oxygen? Lipids 500 What are the elements that make up proteins? What are Carbon, Hydrogen, Oxygen, Nitrogen, and sometimes Sulfur? Proteins 100 What are the monomers of proteins? What are amino acids? Proteins 200 Which protein is not matched correctly with its function? (And give the correct function) A. Enzymes: aid in protection and absorption B. Muscles: movement C. Antibodies: defense against infectious disease D. Hemoglobin: carry and release oxygen to body cells What are enzymes which control the rate of chemical reactions? Proteins 300 The sequence of the amino acid chain for a protein is determined by: What is the sequence in the nucleotides in DNA? Proteins 400 Which diagram below cannot be an amino acid? A B C D What is picture B; it has phosphate so it can’t be an amino acid? Proteins 500 What makes a molecule organic? What is containing 2 or more carbon atoms? Anything Goes in Biochemistry 100 The smallest units or building blocks of larger biomolecules are called- What are monomers? Anything Goes in Biochemistry 200 A student performed several chemical tests of 4 unknown foods. The results are given below. Which unknown is most likely from egg white and why? Chemical Test Unknown A Unknown B Unknown C Unknown D Benedict’s IodineBrown Biuret solution potassium Paper Towel Reagent iodide Test ─ ─ + ─ + ─ ─ ─ ─ ─ ─ + ─ + ─ ─ What is Unknown C because it tested positive (light purple) with Biuret? Anything Goes in Biochemistry 300 A student performed a chemical test on Knox ® gelatin. The results are shown below. Which chemical test was performed and what does it show? What is the Biuret test and the tube on the right tested positive for protein? Anything Goes in Biochemistry 400 A student performed several chemical tests of 4 unknown foods. The results are given below. Which food is most likely a potato and why? Chemical Test Unknown A Unknown B Unknown C Unknown D Benedict’s IodineBrown Biuret solution potassium Paper Towel Reagent iodide Test ─ ─ + ─ + ─ ─ ─ ─ ─ ─ + ─ + ─ ─ What is Unknown D because it turned dark with the IKI? Anything Goes in Biochemistry 500 What type of biomolecule group are enzymes? What are proteins? Enzymes 100 What is the major role of enzymes in the body? What are speed up and control chemical reactions? Enzymes 200 Refer to the diagram below . The products would most likely contain What are simple sugars? Enzymes 300 Why do most enzymes not function properly after being exposed to high temperatures? What is the enzyme has unfolded and the active site can no longer carry out its function? Enzymes 400 Which of the following is TRUE? Enzymes— A. lower the activation energy of a chemical reaction. B. speed up chemical reactions by adding heat to chemical reactions. C. slow down chemical reactions by cooling them off. D. increase the activation energy of a chemical reaction . What is A? Enzymes 500 FINAL JEOPARDY Sam ordered a turkey and cheese sandwich with lettuce, tomatoes, and green peppers? Which biomolecules are represented in the sandwich? What are carbohydrates (bread & veggies), protein (turkey & cheese), lipids (cheese), and nucleic acids (lettuce, tomatoes, and green peppers)? Final Jeopardy 1,000
