1. The first step of Glycolysis is an irreversible regulatory step where glucose is Phosphorylated to glucose-6 phosphate using ATP. The enzyme 1 involved in this step is
pyruvate kinase
phosphoglycerate mutase
Aldolase
Hexokinase

2. The second step of Glycolysis is the conversion of glucose-6-phosphate to fructose 6-phosphate. The enzyme 2 involved in this step is
Phosphofructokinase
Aldolase
Phosphoglucoisomerase
Phosphoglycerate mutase

3.The third step of Glycolysis is an irreversible rate limiting regulatory step where fructose-6-phosphate is phosphorylated to fructose-1,6- bisphosphate using ATP. The enzyme 3 involved in this step is
Phosphofructokinase
Aldolase
Phosphotriose isomerase
Enolase

4. In the fourth step of Glycolysis fructose-1,6-bisphosphate splits into 2, 3-carbon molecules, dihyroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate (GAP). The enzyme 4 involved in this step is
Phosphotriose isomerase
Phosphoglucoisomerase
Aldolase
Enolase

5. In the step 5, dihyroxyacetone phosphate is converted to GAP.The enzyme 5 involved in this step is
Phosphoglycerate mutase
Phosphoglycerate kinase
Phosphotriose isomerase
Pyruvate kinase

6. In the sixth step of Glycolysis, glyceraldehyde 3-phosphate is dehydrogenated to 1,3-bisphosphoglycerate. The enzyme 6 involved in this step is
Phosphoglycerate kinase
Pyruvate kinase
Glyceraldehyde 3-phosphate dehydrogenase
Hexokinase

7. In step 7 of Glycolysis, 1,3-bisphosphoglycerate is hydrolysed to 3-phosphoglycerate by forming ATP. The enzyme 7 involved in this step is
phosphoglycerate kinase
Phosphofructokinase
Aldolase
Phosphotriose isomerase

8. In step 8 of Glycolysis, 3-phosphoglycerate is converted to 2-phosphoglycerate. The enzyme 8 involved in this step is
Aldolase
phosphoglycerate mutase
enolase
pyruvate kinase

9. In step 9 of Glycolysis, 2-phosphoglycerate undergo dehydration forming phosphoenolpyruvate. The enzyme 9 involved in this step is
Enolase
Aldolase
phosphoglycerate kinase
pyruvate kinase

10. The final tenth step of Glycolysis is an irreversible regulatory step where phosphoenolpyruvate is hydrolysed to form pyruvate with the synthesis of ATP. The enzyme 10, final enzme involved in this step is
phosphoglycerate kinase
pyruvate kinase
phosphoglycerate mutase
hexokinase
