6. How many carbon atoms does a hexose sugar contain?

  • 66
  • 8
  • 6
  • 4
  • 20

7. What increases the reactivity of the glucose?

  • Substrate-level phosporylation
  • Two phosphate added to the glucose from two ATP molecules
  • Link reaction

8. Glucose is split into?

  • two molecules of 3-carbon (3C) compounds.
  • three molecules of 2-carbon (2C) compounds.

9. Fill in the blank: 'Each intermediate 3C sugar is.............producing a 3-carbon compound, pyruvate'?

  • denatured
  • oxidised
  • hydrolised
  • decarboxylated
  • oxydenated

10. How many hydrogen atoms are removed are removed during the reaction?

  • 1
  • 2
  • 4
  • 3

11. These removed hydrogen atoms are taken up by the 'coenzyme NAD'.

  • True
  • False

12. What does NAD stand for?

  • nicotinamide adenine dinucleotide
  • nitro adenosine dioside

13. NAD is a non-protein organic molecule.

  • True
  • False

14. Is glucose at a higher or lower energy level than the pyruvate?

  • higher
  • lower

15. ....on conversion this mean that some energy becomes available for:

  • the direct creation of ATP
  • the direct creation of troponin

16. Phosphate from the intermediate compound is transferred to ADP; creating ATP. This is called substrate-level phosporylation?

  • True
  • False

17. How many ATP molecules are gained from glycolysis?

  • 2
  • 1
  • 5
  • 3

18. How many pairs of hydrogen atoms are gained in the reaction?

  • 5
  • 1
  • 3
  • 2
  • 4

19. A net gain of two molecules of 3-carbon pyruvate is yeilded by glycolysis?

  • True
  • False

20. The glycolysis reaction takes place under which conditions?

  • both
  • anaerobic
  • aerobic
