Cellular Respiration


Gluconeogenesis overview: Gluconeogenesis is the process by which glucose is synthesized from noncarbohydrate precursors. The major noncarbohydrate precursors are pyruvate, lactate, glycerol , and glucogenic amono acids. Some body tisssues, such as brain, renal medulla, erythrocytes, lens and cornea of eye, exercising muscle, and testes, require a continuous supply of glucose as a metabolic fuel. Hepatic glycogen can meet these ...

Synthesis of glycogen from glucose is called glycogenesis. Glycogen is the major storage form of glucose in our body that is reserved for future use. Glycogenesis mainly occurs in the liver and skeletal muscle. It takes part in the cytoplasm of cells, and requires energy supplied by adenosine triphosphate (ATP) and uridine triphosphate (UTP). In liver, glycogenesis occurs during periods ...

Pentose phosphate pathway

Pentose phosphate pathway (also called HMP shunt or Hexose monophosphate shunt) is an alternative pathway for glucose metabolism. It does not lead to generation of any ATP. But this pathway has two major functions: (A) generation of NADPH for synthesis of fatty acid and steroid, and (B) formation of ribose for nucleotide and nucleic acid synthesis. Pentose phosphate pathway occurs ...
