Study Notes
Gluconeogenesis
- Certain tissues, including the brain, red blood cells (RBC), and kidney medulla, require a constant supply of glucose as a metabolic fuel.
- Liver glycogen serves as an essential postprandial source of glucose, which can meet the glucose needs of these tissues for a limited period of time.
This quiz covers the process of gluconeogenesis, a metabolic pathway that generates glucose in the body. It is essential for organs like the brain, red blood cells, and kidney medulla.
