Biology 101 Study Guide Exam 1 1. What are the 3 components in the cell theory? 2. What is the valence of these 4 elements: Hydrogen, Oxygen, Nitrogen, and Carbon A. 1,2,3,4 B. 2,4,1,3 C. 1,3,2,4 D. 1,2,4,3 3. What is the difference between covalent and ionic bonds? 4. What is a hydrogen bond? Draw an example. 5. Define electronegativity. 6. What are the unique characteristics of water and what are their biological significance? 7. What type of bond gives water its unique properties? A. Covalent Bond B. Ionic Bonds C. Hydrogen Bonds D. Hydrophobic Bonds 8. What is the mathematical definition of pH? 9. What is the pOH if the pH is 3? 10. What is the change in H concentration if pH changed from 7 to 3? Is it an increase or decrease? 11. What is a hydrocarbon and why is it nonpolar? 12. What are the 3 types of isomers? 13. What are the 6 major functional groups? What characteristics do they have? Draw their shape? 14. What are the 4 types of macromolecules? What are their monomers? What are the bonds and where are they? 15. What is dehydration synthesis? 16. What is hydrolysis? 17. What are the results of a protein being denatured? 18. Draw a phospholipid bilayer and label its parts. 19. Why is starch a source of energy while cellulose is not? 20. What is the difference between a carrier protein and a channel protein? Answer Key 1. All cells come from previous cells, cells are the most basic unit of life, and cells are made up of one or more cells 2. A 3. Covalent bonds share electrons while ionic bonds transfer electron Or covalent bonds occur between nonmetals and ionic bonds occur between a metal and non metal 4. A bond that forms between a partially (+) charged hydrogen and a partially () atom 5. The tendency for an atom to attract electrons 6. High Specific Heat allows organisms to resist drastic change in heat and stabilizes oceans and lakes Water expands when it freezes allows marine life to survive during winter because the ice floats and the lake or ocean won’t freeze solid Water is the biological solvent 7. C 8. pH= log [pH ] + 9. pOH=11 [pH] + [pOH] = 14 Initial – Final 10. Increase by 10000 10 11. A molecule composed of only carbon and hydrogen. It is nonpolar because carbon and hydrogen have a similar electronegativity. 12. Structural, Geometric, Stereoisomer 13. Answer is further Down 14. Answer is further Down 15. Combining monomers by removing water 16. Separating monomers by adding water 17. When a protein denatures, it loses it shape and does not function anymore 18. 19. Starch is a source of energy because it forms alpha bonds with other monosaccharides 20. Carrier protein can be either active or passive while channel is always passive 13. 14. Macromolecule: Protein Monomer: Amino Acids Bond: Peptide Bonds Amino Acid Peptide Bond Macromolecule: Carbohydrate Monomer: Monosaccharide/ Simple Sugar Bond: Glycosidic Bond Monosaccharide Glycosidic Bond Macromolecule: Lipid Monomer (Note: There are 2): Fatty Acid and Glycerol Bond: Ester Bond Glycerol Ester Bond Fatty Acid Macromolecule: Nucleic Acid Monomer: Nucleotide Bond: Phosphodiester Nucleotide Phosphodiester Bond
