Figure 10-2 The interconversion of glucose, glycogen, and glyceraldehyde-3-phosphate in the pathways of glycolysis, gluconeogenesis, and glycogen synthesis. Pathways of catabolism are indicated with black lines and those of biosynthesis with green lines.

Summary of some interconversions and synthetic reactions in which amino sugars participate. Substrates for the pathway can be derived from glucose, glycogen, and gluconeogenesis.

Storage and utilization of tissue glycogen, maintenance of blood glucose concentration, and other aspects of carbohydrate metabolism are meticulously regulated by hormones, including insulin, glucagon, epinephrine, and the glucocorticoids.

Insulin is secreted as a direct response to hyperglycemia it stimulates the liver to store glucose as glycogen and facilitates uptake of glucose into extra-hepatic tissues. 

In starvation, glucose must be ptovided for the brain and erythrocytes initially, this is supphed from hver glycogen reserves. To spare glucose, muscle and other tissues reduce glucose uptake in response to lowered insuhn secretion they also oxidize fatty acids and ketone bodies preferentially to glucose. 

Glucose derived from muscle glycogen and metabolized by anaerobic glycolysis is the major fuel source. Blood glucose and free fatty acids are the major fuel sources. 

Carbohydrates are an important food source for most organisms. Glucose, fructose, and sucrose are small carbohydrate molecules that can be broken down rapidly to provide quick energy for cells. Large amounts of energy are stored in carbohydrate macromolecules called polysaccharides. For example, glycogen is a polysaccharide used... 

C13-0069. Glycogen and cellulose are both polymers of glucose. Explain why humans can use glycogen but not cellulose as an energy source. Why can cows digest cellulose, but humans cannot ... 

Since the cornea derives its eneigy from the breakdown of glycogen and glucose, it requires oxygen, which it derives from the atmosphere, the tears and from the aqueous humour. A high concentration of lactate is built up, which is eventually removed by passage into the aqueous humour. 

Carbohydrates are classified based upon the products formed when they are hydrolyzed. Monosaccharides are simple sugars that cannot be broken down into simpler sugars upon hydrolysis. Examples of monosaccharides are glucose, ribose, deoxyribose, and fructose. Disaccharides contain two monosaccharide units and yield two monosaccharides upon hydrolysis. Examples of disaccharides are lactose, maltose, and sucrose. Polysaccharides are polymers of monosaccharide units and yield many individual monosaccharides upon hydrolysis. Examples of polysaccharides are starch, glycogen, and cellulose.
