Glycolysis Process

Question 1

1. What are the two phases that Glycolysis can be divided into?

Answer 1

The so-called preparation phase and the ATP generating phase

Question 2

2. What is the first reaction of the glycolytic pathway/ what happens?

Answer 2

Glucose is phosphorylated to glucose-6-phosphate

Question 3

3. What is glucose isomerised to?

Answer 3

Fructose-6-phosphate

Question 4

4. What is Fructose-6-phosphate phosphorylated to form?

Answer 4

Fructose-1,6-biphosphate

Question 5

5. What splits Fructose-1,6-biphosphate and into what?

Answer 5

This molecule is split by aldolase into glyceraldehyde-3-phosphate and dihydroxyacetone phosphate

Question 6

6. What is special about glyceraldehyde-3-phosphate and dihydroxyacetone phosphate

Answer 6

They are interconvertible

Question 7

7. glyceraldehyde-3-phosphate is oxidized and phosphorylated to form?

Answer 7

1,3 - bis-phospho -glycerate

Question 8

8. What is 1,3 - bis-phosphoglycerate converted into

Answer 8

3 - phosphoglycerate (ATP is produced in this step)

Question 9

9. What is 3 - phosphoglycerate isomerised into?

Answer 9

2-phosphoglycerate

Question 10

10. What does the removal of water from 2-phosphoglycerate generate

Answer 10

Phosphoenolpyruvate (this compound is used again to produce ATP forming pyruvate)
