  3. What ratio do we find in carbohydrates? • 1 H:2 O • 2 C:2 H • 2C:2 O • 2 H:1 O

  4. If a solution turned navy blue with the iodine test, what substance would it indicate? • Monosaccharide • Disaccharide • Polysaccharide • Protein

  5. The functional group for carbohydrates? • Hydroxyl group • Carboxyl group • Amino group • Alcohol group

  6. The functional group for proteins is the • Hydroxyl group • Carboxyl group • Amino group • Both B and C

  7. 6. The function of carbohydrates is to • Provide structure • Give instructions to the cell • Provide energy • Control chemicals

  10. In what organic substance(S) can the amino function group be found in? • Proteins • Amino acids • Carbohydrates • Lipids • A & B

  11. A train car is to a freight train as a(n) ___________ is to a nucleic acid • Polymer • Amino acid • Nucleotide • Protein • Polysaccharide

  12. Starch, cellulose, and glycogen are examples of… • Macromolecules • Simple sugars • Disaccharides • Quick energy molecules

  13. How do our bodies use fats? • To store energy • To protect organs • As insulation • To store vitamins • All of the above

  14. In order to form a protein, what has to happen? • Multiple monosaccharides have to join together by losing water • Multiple disaccharides have to join together by adding water • Multiple monomers have to join together by losing water • Multiple amino acids have to join together by adding water

  15. True or false: a condensation reaction is the same as a hydrolysis reaction. • True • False

  16. When a substrate fits into an enzyme and the enzyme forms around the substrate this… • Is called the Lock and Key Hypothesis • A coenzyme is needed • Is called the Induced Fit Hypothesis • An inhibitor is present

  17. What happens in noncompetitive inhibition? • The inhibitor competes with the substrate for the active site • The inhibitor bonds permanently with the enzyme • The inhibitor reversibly binds with the substrate • The inhibitor binds with the enzyme at a place other than the active site

  18. Pesticides, poisons, mercury, and lead are examples of… • Reversible inhibitors • Irreversible inhibitors • Noncompetitive inhibitors • Competitive inhibitors

  20. Saturated fats are… • Of animal origin • Made of single bonds between carbons • Recognized as butter, lard, and coconut oil • A & B only • All of the above

  21. When the body needs energy in what order does it use the organic compounds? (from first to last) • Fats, carbohydrates, proteins • Carbohydrates , proteins, fats • Fats, proteins, carbohydrates • Carbohydrates, fats, proteins

  22. Unsaturated fatty acids… • are considered “bad fats” • Come from animals • Have at least one double bond in their fatty acid chains • Have only single bond in their fatty acid chains

  23. A Peptide bond forms between • Carbon and oxygen • Carbon and carbon • Nitrogen and hydrogen • Oxygen and nitrogen • Carbon and nitrogen

  24. Which of the following represents a correct equation for hydrolysis? A. C6H12O6 + C6H12O6 + enzymes→ C12H22O11 + H2O B. C12H22O11 + H2O + enzymes→ 2 C6H12O6+ energy C. C6H12O6 + C6H12O6 + energy + enzymes→ C12H22O11 D. C12H22O11 + 3 H2O → 3 C6H12O6
