Biochemistry Test Review Sheet What do all organic compounds have in common? They contain Carbon and Hydrogen Match the following macromolecules with the examples for in that category Carbohydrate A. Enzymes, hemoglobin, antibodies, hair Lipid B. DNA, RNA, ATP Protein C. starch, glucose, cellulose Nucleic Acid D. fatty acids, phospholipids, cholesterol Match the following macromolecules with the correct function. Carbohydrate A. short term energy source Lipid B. structure, antibodies, enzymes, hormones Protein C. long term energy source Nucleic Acid D. stores hereditary information Match the following macromolecules with the correct subunit. Carbohydrate A. nucleotides Lipid B. monosaccharides Protein C. fatty acid chains Nucleic Acid D. amino acids 5. Relate the terms monomer and polymer. Polymers are like many monomers built up together. 6. Complete the chart below. Macromolecule Monomer (subunit) Function Carbohydrates monosaccharide Main source of short-term energy Drawing Lipids Glycerol and fatty acids Main source of long-term energy Carries out Proteins all amino acids of the bodies processes Nucleic Acids nucleotides Stores and transmits genetic information 7. Relate the terms catalyst and enzyme. An enzyme is a type of catalyst. 8. Draw and label an enzyme, substrate, and active site. Define activation energy and EXPLAIN it using an example. Tell me what an enzyme does. An enzyme speeds up chemical reactions by lowering the activation energy. H uge changes in temperature and pH cause a protein to change shape . What do you think the effect would be if we changed the shape of an enzyme? The effect of changing the shape of an enzyme is that the substrate won’t be able to fit in it anymore. Match each of the bonds with their description: Polar A. Attraction of two polar molecules Nonpolar B. Unequal sharing of electrons causes +/poles Hydrogen C. Equal sharing of electrons Below is a water molecule . Label Hydrogen, Oxygen, + pole, - pole. Lipids have a lot of non-polar bonds . Water has polar-bonds. Using this information, tell me why oil and water don’t mix. Because polar bonds are easier to mix with other polar bonds. 15. Draw a picture of a sugar cube in coffee. Label the solution, solvent, and solute. (once mixed) 16.Contrast adhesion and cohesion. Adhesion is when water sticks to other substances. Cohesion is when water sticks to other water molecules. Below is a pH scale . Color the acidic side red, the basic side blue, and the neutral part yellow . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Water has a high specific heat . What does this say about the temperature of water? This means that it is difficult to lower and raise this heat. Contrast metabolism and homeostasis. Metabolism is all the processes occurring in your body, while homeostasis is stabilizing the right conditions for your body. Define each of the following: Independent variable : This affects the dependent variable, and it is what you change . Dependent variable : This is what is changed by the independent variable. Control : This is what you use to even out the experiment. Constant : This is what you keep the same .
