CHEM 210 Module 1

  1. True or False: According to the Module, a compound with a molecular mass of 1,000 g/mol is considered a macromolecule. ANS False
  2. True or False: Biomolecules can have only two functional groups. ANS False
  3. True or False: In a eukaryotic cell, the organelles called ribosomes serve the purpose of digesting macromolecules. ANS False
  4. True or False: Carbon dioxide has a linear molecular shape AND has a bond angle of 109.5 degrees ANS False
  5. is a functional group found in carbohydrates. ANS alcohol

12. For an organic compound, which structure is the most efficient to draw?- ANS line bond

  1. When writing an organic functional group, scientists often write an "R" as part of the structure. What does the R indicate? ANS rest of the molecule
  2. According to the module, the study of NON-carbon compounds is referred to as. ANS inorganic
  3. Which number would be closest to the approximate number of ribosomes in an E. coli cell? ANS 26,
  4. Which of the following would most likely have a cell wall? ANS fungal cells
  1. Eukaryotes have molecules that provide a protective structure. This net- work, which is found in all eukaryotes, is called the. ANS cytoskele- ton
  2. The molecule linked to the medical condition of gout is. ANS uric acid
  3. About how many different elements are found in living organisms? ANS 30
  4. Explain the common similarity in all prokaryotic and eukaryotic cells. Explain the similarity in at least two sentences. ANS The fundamental similarity is that 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). The plasma membrane permits the cell to have a different composition of molecules inside the cell than out and defines a space for life to occur.

by forming numerous carbon-carbon bonds; we call these large molecules polymer. 4. Lastly, carbon can form cyclic structures, which are also called ring compounds.

  1. (Short response) What the definition of inorganic chemistry? How does it differ from organic chemistry? ANS Inorganic chemistry is the study of all other ele- ments, but carbon. Organic chemistry is the study of carbon-based compounds both in living and non-living organisms. There is no need to have separate sub-disciples for organic and inorganic chemistry, but for historical and organizational reasons, the difference exists.
  2. (Short response) Biochemists study the chemical reactions of organisms. According to the module, what are two other aspects of living organisms that biochemists study? ANS In the module, biochemists also study the structure and function of biomolecules and communication within and among organisms.
  3. are abundant in living organisms (bulk elements) ANS Elements including car- bon, oxygen, nitrogen, sulfur, and hydrogen
  4. Stable bonds allow cells to ANS form, hair to grow, and skin to protect against abrasion.
  5. "medium of life" ANS water
  1. shape of water ANS bent 104.5 degrees
  2. critical to all living things and is found in large amounts. ANS carbon
  3. name One advantage of cyclic carbon compounds ANS is that they are more restricted in their movements and orientation—a property that is advantageous for building structures and maintaining shape.
  1. functions primarily to form lipids ANS smooth ER
  2. single-membrane glob-like organelle that contains a suite of enzymes that "detoxify" dangerous or hazardous molecules. ANS peroxisome
  3. In animal cells, the digestive center is an organelle called a ANS lysosome
  4. is the conversion of glucose to ATP, ANS respiration
  5. What is the bond angle associated with trigonal pyramidal shape? ANS 107.
  6. Are transition metals commonly found in biological organisms? ANS yes they are trace elements 48. True or false Water can make up 85% (by mass) of a living organism. ANS 49. True. Some plants are made up of 90% water by mass. ANS 50. True or false Large elements tend to make the strongest covalent bonds. ANS

False. Smaller elements tend to make the strongest bonds due to significant overlap.

  1. Name three bulk elements. Name three trace elements. ANS Bulk elements (three of these) H, C, N, O, Na, P, S, Cl, K, and Ca Trace elements Mg, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Mo, I, and W.
  2. Is H2O an organic molecule? How about CO2? C100H202? ANS Water is not

or- ganic; it does not contain carbon. Both CO2 and C100H202 are organic compounds.

  1. How are the aldehyde and ketone functional groups similar? Different? ANS - Aldehdyes and ketones both have a carbon double bond oxygen arrangement (C=O) in their structure. They differ in that the other two bonds that the carbon forms are different. A ketone has both bonds connected to other carbons. An aldehyde has one bond to hydrogen and the second bond to either another hydrogen or carbon.
  2. What functional groups are found in glycine? ANS Carboxylic acid and amine

closely related to prokaryotes.

  1. What is the function of mitochondria, lysosomes, and vacuoles? ANS The mito- chondria is the powerhouse of the cell responsible for producing ATP. It also contains metabolic processes that yield ATP in the end. Lysosomes degrade macromolecules-protein, lipid, carbohydrate, nucleic acids-into smaller pieces. These organelles have an acidic pH. Vacuoles have digestive enzymes to degrade proteins, carbohydrates, and nucleic acids, plus vacuoles function largely as storage centers.
  2. What energy molecule is produced in the mitochondria? ANS ATP
