5 Matching questions

  1. monomer
  2. condensation reaction
  3. double helix
  4. cellulose
  5. fatty acid
  1. a A structural polysaccharide of cell walls, consisting of glucose monomers joined by b-1, 4-glycosidic linkages
  2. b The subunit that serves as the building block of a polymer
  3. c The form of native DNA, referring to its two adjacent polynucleotide strands wound into a spiral shape
  4. d 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
  5. e A reaction in which two molecules become covalently bonded to each other through the loss of a small molecule, usually water; also called dehydration reaction

5 Multiple choice questions

  1. a nitrogenous base that has a double-ring structure; one of the two general categories of nitrogenous bases found in DNA and RNA; either adenine or guanine
  2. A steroid that forms an essential component of animal cell membranes and acts as a precursor molecule for the synthesis of other biologically important steroids
  3. A polymer of up to over a thousand monosaccharides, formed by condensation reactions
  4. An extensively branched glucose storage polysaccharide found in the liver and muscle of animals; the animal equivalent of starch
  5. A chemical process that lyses, or splits, molecules by the addition of water; an essential process in digestion

5 True/False questions

  1. monosaccharideThe simplest carbohydrate, active alone or serving as a monomer for disaccharides and polysaccharides. Also known as simple sugars, the molecular formulas of monosaccharides are generally some multiple of CH20


  2. alpha helixThe form of native DNA, referring to its two adjacent polynucleotide strands wound into a spiral shape


  3. geneA double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins


  4. DNAA type of nucleic acid consisting of nucleotide monomers with a ribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and uracil (U); usually single-stranded; functions in protein synthesis and as the genome of some viruses


  5. primary structurethe level of protein structure referring to the specific sequence of amino acids
