Final answer:
Gluconeogenesis is the process in the body that produces glucose internally when blood glucose levels decrease. It primarily occurs in the liver during periods of low glucose, such as fasting or low carbohydrate diets. Gluconeogenesis synthesizes new glucose molecules from non-carbohydrate sources to maintain a minimum blood glucose concentration.
Step-by-step explanation:
Gluconeogenesis is the process in the body that produces glucose internally when blood glucose levels decrease. It primarily occurs in the liver during periods of low glucose, such as fasting or low carbohydrate diets. Gluconeogenesis synthesizes new glucose molecules from non-carbohydrate sources like pyruvate, lactate, glycerol, or certain amino acids. This ensures that the body maintains a minimum blood glucose concentration to provide energy for glucose-dependent organs like the brain.
