  • The following is an illustration of the glycolysis pathway:
  • Of the steps illustrated how many are unidirectional? Identify the substrate and product of each of these steps. (4 pts)
  • Identify the three enzymes that are likely to be regulated? (3 pts)
  • Glycogen synthase is an enzyme that catalyzes the synthesis of glycogen from glucose. Glucose 6 phosphate activates glycogen synthase by allosteric regulation. In your own words describe how this allosteric modulation is likely to occur? (4pts)
  • Glycogen phosphorylase, an enzyme that catalyzes the breakdown of glycogen to form glucose, is active when a phosphate group is added. This is an example of enzyme regulation by ____________________________. (2pts)
  • An example of a coenzyme that regulates succinate dehydrogenase is ______________________ (2pts)
