1

First step of glycolysis? Enzyme involved?

Glucose --> Glucose 6 phosphate

hexokinase

2

glucose 6 phosphate ---> ?
enzyme?

fructose 6 phosphate

phosphohexose isomerase

3

fructose 6 phosphate ---> ?
enzyme?

fructose 1,6 phosphate

phosphofructokinase 1

4

fructose 1,6 phosphate ---> ?
enzyme?

2 products:
Dihydroxyacetone phosphate
Glyceraldehyde 3 phosphate

both via aldolase

5

Dihydroxyacetone phosphate ---> ?
enzyme?

Glyceraldehyde 3 phosphate

triose phosphate somerase

6

Glyceraldehyde 3 phosphate ---> ?
enzyme?

1,3 bisphosphoglycerate

glyceraldehyde phosphate dehydrogenase

7

1,3 bisphosphoglycerate ---> ?
enzyme?

3 phosphoglycerate

phosphoglycerate kinase

8

3 phosphoglycerate ---> ?
enzyme?

2 phosphoglycerate

phosphoglycerate mutase

9

2 phosphoglycerate ---> ?
enzyme?

phosphoenol pyruvate

enolase

10

phosphoenol pyruvate ---> ?
enzyme?

pyruvate

pyruvate kinase

11

how many molecules of pyruvate do you get from 1 glucose molecule

2 pyruvate molecules

12

which steps of glycolysis take ATP?

step 1: glucose -> glu 6 phos

step 3: fructose 6 phos -> fructose 1,6 phos

13

which steps produce ATP?

1,3 bisphosphoglycerate -> 3 phosphoglycerate (x2)

phosphoenol pyruvate -> pyruvate (x2)

note: there are two molecules of these steps so in total, 4 ATP is prduced (2 net atp)
