decarboxylation and dehydrogenation

• what is decarboxylation


  this is a chemical reaction in which a carboxyl group is split off from a compound as CO2
• what is used to help speed up decarboxylation reactions


  decarboxylase enzymes
• what is dehydrogenation


  The removal of hydrogen from a molecule
• what is used to help speed up dehydrogenation reactions


  dehydrogenase enzymes
• give examples of places where decarboxylation occurs


  when pyruvate is converted into acetate in the link reactions and when 6C is converted into 5C and then 5C into 4C in the Krebs cycle
• give examples of places where dehydrogenation occurs


  when triose phosphate is converted into pyruvate in a glycolysis reaction and when pyruvate is converted into acetate in the link reaction
