5 Matching questions

  1. polymer
  2. carbohydrate
  3. nucleic acid
  4. lipid
  5. gene
  1. a A sugar (monosaccharide) or one of its dimers (disaccharides) or polymers (polysaccharides).
  2. b A long molecule consisting of many similar or identical monomers linked together
  3. c 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
  4. d One of a family of compounds, including fats, phospholipids, and steroids, that are insoluble in water
  5. e A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses)

5 Multiple choice questions

  1. A three-dimensional biological polymer constructed from a set of 20 different monomers called amino acids
  2. a type of lipid that consists of four carbon rings to which various functional groups are attached
  3. A structural polysaccharide of an amino sugar found in many fungi and in the exoskeletons of all arthropods
  4. the level of protein structure referring to the specific sequence of amino acids
  5. The 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

5 True/False questions

  1. disaccharideA polymer of up to over a thousand monosaccharides, formed by condensation reactions

          

  2. condensation reactionA reaction in which two molecules become covalently bonded to each other through the loss of a small molecule, usually water; also called dehydration reaction

          

  3. triacylglycerolA steroid that forms an essential component of animal cell membranes and acts as a precursor molecule for the synthesis of other biologically important steroids

          

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

          

  5. peptide bonda type of lipid that consists of four carbon rings to which various functional groups are attached
