8 Main Glycolytic Reactions | Carbohydrates | Biochemistry

The following points highlight the eight main glycolytic reactions. The reactions are: 1. Phosphohexose Isomerase 2. Phosphofructokinase 3. Aldolase or Fructose-Bisphosphate Aldolase 4. Glyceraldehyde-3-℗ Dehydrogenase 5. 3-Phosphoglycerate Kinase 6. Phosphoglycerate Mutase 7. Enolase 8. Pyruvate Kinase. Reaction # 1. Phosphohexose Isomerase: This enzyme isomerizes glucose-6-℗ (resulting, via glucose-1-℗, from phos-phorolysis of the reserve glycogen or from the phosphorylation of glucose [...]

Oxidative Decarboxylation of Pyruvic Acid | Biochemistry

In this article we will discuss about the oxidative decarboxylation of pyruvic acid. We know that anaerobiosis the pyruvic acid formed during glycolysis reacts with NADH which accumulates to give lactic acid (or ethanol) and thus permits the regeneration of NAD+. But when oxygen is available, NADH is reoxidized thanks to the electrons carrier system, and the pyruvic acid is [...]

Transformation of Pyruvic Acid | Carbohydrates

The following points highlight the three possibilities of the transformation of pyruvic acid. The possibilities are: 1. Production of Lactic Acid 2. Alcoholic Fermentation 3. Formation of α-Glycerophosphate and Glycerol. Possibility # 1. Production of Lactic Acid: In animals, in muscle cells (where anaerobiosis conditions often prevail when oxygen utilization is more rapid than its input in cells) or in [...]
