Question

9. The types of reactions catalyzed by the enzymes involved in glycolysis include—

A) dehydration. B) isomerization. C) phosphorylation. D) carbon-carbon bond cleavage. E) all of the above

Answer 1

Ans. 9- E option is correct. All of the above.

Phosphorylation reaction occur in glycolysis because glucose is phosphorylated to form glycose- 6- phosphate. This reaction is catalyzed by glucokinase enzyme.

Isomerization reaction involve in glycolysis when isomerization of glucose-6-phosphate to fructose-6-phosphate occur. This reaction catalyzed by phosphohexose isomerase enzyme.

Dehydration of 2- Phosphoglycerate to Phosphoenolpyruvate occur during glycosis.

Cleavage of Fructose 1,6- Bisphosphate also occur in glycolysis and in this reaction carbon- carbon bond cleavage occurs that produce Dihydroxyacetate phosphate and Glyceraldehyde-3-phosphate.
