5 Matching questions

  1. fatty acid
  2. alpha helix
  3. cellulose
  4. monomer
  5. steroid
  1. a a long carbon chain carboxylic acid. fatty acids vary in length and in the number and location of double bonds; three fatty acids linked to a glycerol molecule form fat
  2. b The subunit that serves as the building block of a polymer
  3. c a type of lipid that consists of four carbon rings to which various functional groups are attached
  4. d A spiral shape constituting one form of the secondary structure of proteins, arising from a specific hydrogen-bonding structure
  5. e A structural polysaccharide of cell walls, consisting of glucose monomers joined by b-1, 4-glycosidic linkages

5 Multiple choice questions

  1. An organic molecule possessing both carboxyl and amino groups. Amino acids serve as the monomers of proteins
  2. A chemical process that lyses, or splits, molecules by the addition of water; an essential process in digestion
  3. A polymer of up to over a thousand monosaccharides, formed by condensation reactions
  4. A polymer (polynucleotide) consisting of many nucleotide monomers; serves as a blueprint for proteins and, through the actions of proteins, for all cellular activities. The two types are DNA and RNA
  5. A polymer (chain) of many amino acids linked together by peptide bonds
