During glycolysis, ATP is formed and used in the following reactions (Refer Table 8.1): Table 8.1 Production of High-energy Phosphate in the Catabolism of Glucose The net gain of ATP molecules during glycolysis is eight as seen from the table (10 – 2 = 8). During anaerobic condition, NAD+ is regenerated from NADH by the reduction of…
Glycolysis occurs in all cells, and in some cells, it is the sole source of energy like brain cells, erythrocytes. Organelle: It occurs in cytoplasm of the cells. Steps Glycolysis is also called Embden Meyerhof pathway. In glycolysis, the breakdown of the six-carbon glucose into two molecules of the three-carbon pyruvate occurs in ten steps, Glycolysis…

Figure 8.6 Outline of Glycolysis
INTRODUCTION Glycolysis was derived from the Greek words glykys, which means sweet, and lysis, which means splitting. In the process of glycolysis a molecule is catabolised in a series of reactions to yield two molecules of three-carbon compound called pyruvate. In the glycolysis pathway, a series of reaction takes place during which some of the energy is released…
The location and integration of metabolic pathways are released by studies at lower levels of organisation, namely the following: At the tissue and organ level, the blood circulation integrates metabolism. Amino acids resulting from digestion of dietary protein and glucose resulting from the digestion of carbohydrate share a common route of absorption via the hepatic…
Amino acids are necessary for protein synthesis. Some must be supplied specifically in the diet (the essential amino acids) since the tissues are unable to synthesis them. The reminder or non-essential amino acids are also supplied in the diet, but they can be formed from intermediates by transamination using the amino nitrogen from other surplus…
The source for the fatty acid synthesis is acetyl-CoA. Fatty acid is produced either by de novo synthesis from acetyl-CoA derived from carbohydrate or from dietary lipid. In the tissues, fatty acids are oxidised to acetyl-CoA (β-oxidation) or esterified to acylglycerol, whereas in triacylglycerol (fat), they constitute the body’s main caloric reserve. Acetyl-CoA formed by…
