  6. Of the following, is not a property of carbon.: possessing five valence electrons
  7. Which of the following is an element not typically found in living organisms?-

2 / : He

  1. is a functional group found in carbohydrates.: Alcohols
  2. The following functional group is an example of .: Ketone
  3. A is a chemical formula that does NOT show the C-H and C-C bonds.: Condensed formula
  4. A collection of two or more macromolecules uniting is called a .: - Supramolecular complex
  5. An organic compound with this structure, C=C, contains a functional group.: Alkene
  6. Scientists refer to as the "super glue" of the chemistry.: C
  7. What molecule is most important for energy storage in cells?: ATP
  8. What would be the approximate size of a human cell?: 12 μm
  9. For propane, there carbon and

  1. Which number would be closest to the approximate number of ribosomes in an E. coli cell?: 25,
  2. Which of the following would most likely have a cell wall?: Marigold flower cells
  3. Eukaryotes have molecules that provide protective structural. This network is called the .: Cytoskeleton
  4. The molecule linked to the medical condition of gout is .: Uric acid
  5. About how many different elements are found in living organisms?: 30
  6. (Short response) Explain the common similarity in all prokaryotic and eukary- otic cells. Give a brief explanation of the similarity.: Each cell type has a plasma membrane that separates life from non-life. The plasma membrane acts as a barrier to most molecules but does have proteins that permit select molecules to cross via proteins (transporters).
  7. (Short response) Would scientists be more likely to find an element such as O in a biomolecule, or W? Explain which she would

5 / more likely find in biological molecule and give specific physical/chemical properties.: She would more likely find O. Smaller elements are preferred. Smaller elements with smaller atomic shells are favored because they can form stable covalent bonds, allowing cells to form, hair to grow, and skin to protect against abrasion.

  1. (Short response) What element is the basis for life? Describe at least two properties of this element that permit it to serve the basis for life.: 1. Carbon can form strong covalent bonds with a variety of ditterent elements. 2. Carbon can form double and triple bonds with other carbon atoms and other elements (N and o).
  2. (Short response) How does organic chemistry differ from inorganic chem- istry?: Organic chemistry is the study of the carbon-based compounds. Inorganic chemistry is the study of all other elements, but carbon.
  3. (Short response) Biochemists study the communication within and among organisms. According to the module, what are two other aspects of living or- ganisms that biochemists study?: Biochemists also study the structure and function of biomolecules and the chemical reactions of organisms.
