Glycolysis

Question 1

Describe the overall reaction of Glycolysis

Answer 1

Glucose to 2x Pyruvate producing net 2 ATP and 2 NADPH

Question 2

Name the enzymes responsible for using ATP in the pathway

Answer 2

Hexokinase, Phosphofructokinase

Question 3

Name the enzyme that converts glucose-6-phosphate Into fructose-6-phosphate

Answer 3

Phosphoglucose isomerase

Question 4

What is the name of the enzyme in glycolysis that converts one reactant into products?

Answer 4

Aldolase

Question 5

Name the two products of the reaction catalysed by aldolase

Answer 5

Glyceraldehyde 3 phosphate

Dihydroxyacetone phosphate

Question 6

What enzyme is used to convert dihydroxyacetone phosphate into glyceraldehyde 3 phosphate?

Answer 6

Triose Phosphate Isomerase

Question 7

What type of enzyme converts glyceraldehyde 3 phosphate into one three bisphosphoglycerate?

Answer 7

(Glyceraldehyde 3 phosphate) Dehydrogenase

Question 8

Describes the two reactions in Glycolysis where ATP is produced

Answer 8

1,3-bisphosphoglycerate to 3-phosphoglycerate by phosphoglycerate Kinase
Phosphoenolpyruvate to pyruvate via Phosphoenolpyruvate kinase

Question 9

Where in glycolysis is NADH produced?

Answer 9

In the conversion of Glyceraldehyde 3 phosphate to 1,3-bisphosphoglycerate by Glyceraldehyde 3 phosphate Dehydrogenase

Question 10

Which Enzyme changes the position of the phosphate group on glycerate

Answer 10

Phosphoglycerate mutase

Question 11

What does the enzyme enolase do?

Answer 11

Converts 2-phosphoglycerate to Phosphoenolpyruvate

Question 12

Where does glycolysis occur?

Answer 12

In the cytoplasm

Question 13

What is the property hexokinase that makes it significant in glycolysis?

Answer 13

The reaction it catalyses is nearly irreversible so glucose is locked into glycolysis.
