Study Notes
Gluconeogenesis Definition & Site
- Gluconeogenesis is the process of creating glucose or glycogen from non-carbohydrate sources.
- Major sources for this process include lactate, pyruvate, glucogenic amino acids, propionate, and glycerol.
- Gluconeogenesis primarily occurs in the cytosol but some precursors are made within the mitochondria.
- The liver is the main location for gluconeogenesis, with the kidneys playing a secondary role.
Importance of Gluconeogenesis
- The brain, central nervous system, erythrocytes, testes, and kidney medulla rely solely on glucose for energy needs
- Glucose is the only source for providing energy to skeletal muscle and red blood cells during anaerobic conditions.
