5 True/False Questions

  1. RNAMostly single stranded; uracil in place of thymidine; mRNA; rRNA, tRNA


  2. Ketoseglucose and galactose


  3. Activation EnergyNeeded to disrupt electronic configurations; physiological temperature and pressure too low for most chemical reactions to take place. Enzymes serve to speed up reactions by lowering activation energy.


  4. DNAMostly single stranded; uracil in place of thymidine; mRNA; rRNA, tRNA


  5. ProteinsMade up of repeating units of amino acids (about 20 types); Subunits linked by peptide bonds forming polymers; Function: structural support, antibodies, contractile fibers, toxins, transport.
