Glycolysis

Glycolysis is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates. This powerpoint Presentation includes all steps of glycolysis.

1. Glycolysis Vikas Kashyap M.Sc (G&PB) Chaudhary Charan Singh University

2. Glycolysis Glycolysis is first metabolic step of carbohydrates in which one molecule as glucose is breakdown into pyruvate, lactic acid and produce ATP. It is a Universal Pathway given by Embden, Mayerhof and Parnas ; thus often known as EMP Pathway. Glycolysis is an anerobic process . Site of glycolysis - Cytosol

3. Step 1 Glucose reacts with hexokinase by using ATP and convert into Glucose 6- Phosphate Kinase: It is an enzymes which act phosphorylation.

4. Step 2 Glucose 6- Phosphate again reacts with Phosphohexos isomerase to convert it into Fructose 6 Phosphate. Isomerase: This is a general class of enzymes which convert a molecule from one isomer to another.

5. Step 3 Fructose 6 Phosphate react with Phosphofructo kinase and convert it into Fructose-1, 6-bisphosphate .

6. Step 4 Fructose-1, 6-bisphosphate reacts with aldolase and breaks down into two parts Glyceraldehyde-3-phosphate (G3P) and Dihydroxy acetone phosphate (DHAP). Aldolase: is an enzyme that helps to break down to sugar to produce energy.

7. Step 5 Isomerization of dihydroxyacetone phosphate (DHAP) into glyceraldehyde 3 phosphate (G3P). Because only G3P can be used further in glycolysis.

8. Step 6 Glyceraldehyde 3 phosphate converts into 1, 3-bisphosphoglycerate by the help of Glyceraldehyde 3-phosphate dehydrogenase .

9. Step 7 The enzyme phosphoglycerate kinase acts on 1, 3-bisphosphogycerate coverts into 3-phosphoglycerate .

10. Step 8 3-Phosphoglycerate is converted into 2-phosphoglycerate by phosphoglycerate mutase .

11. Step 9 2-Phosphoglycerate reacts with Enolase and it converts into Phosphophenol pyruvate .

12. Step 10 Phosphoenol pyruvate react with Pyruvate kinase and it convert Pyruvate and also produce ATP .
