6. PEPCK is regulated via transcriptional and protein expression rates

  • True
  • False

7. Pyruvate is...

  • A precursor of the citric acid cycle, a product of glycolysis and a precursor of gluconeogenesis
  • A hetero-dimer would be formed by two different macromolecules (process called heterodimerization)

8. Amylase enzymes are needed in the human intestine to _______

  • Digest plant starch
  • Digest animal glycogen

9. The levels of PEPCK activity regulate the rate of gluconeogenesis

  • True
  • False

10. Gluconeogenesis is

  • The reverse pathway of glycolysis
  • Another name for glycolysis

11. In response to high glucose levels ________ is released

  • Insulin
  • Glucagon

12. Glycolysis regulation: Elevated levels of AMP or ATP - would this inhibit or stimulate glycolysis?

  • Elevated levels of AMP – stimulation of glycolysis, elevated ATP - inhibition of glycolysis
  • Elevated levels of AMP – inhibtion of glycolysis, elevated ATP - stimulation of glycolysis

13. Why would high acetyl CoA levels stimulate oxaloacetate formation?

  • Skeletal muscle
  • High acetyl Co A levels stimulate pyruvatecarboxylase activities, which catalyses the reaction to form oxaloacetate
  • The process of breaking a 1, 4 glycosidic bonds

14. Phosphorolysis

  • The process of breaking a 1, 4 glycosidic bonds
  • The process of breaking a 1, 6 glycosidic bonds

15. A debranching enzyme that hydrolyses a 1,6 glycosidic bonds

  • Glucosidase
  • Glycogenesis
  • Glucose

16. How many molecules of ATP are produced by glycolysis

  • Three
  • Four
  • Two
  • Ten

17. Glycogen catabolism in mammals is

  • Glycogenolysis
  • Glycogen synthase

18. Glycogen is produced via

  • Glycogenesis
  • Glucogenolysis

19. Glucose can be synthesised from ________

  • Lactate
  • Tryptophan

20. Glycogen is composed of (monosaccaride)

  • Glucosidase
  • Glycogenesis
  • Glycogen
