Study Notes
Hormonal Regulation of Blood Glucose
- Insulin decreases blood glucose levels by facilitating the uptake of glucose into cells and promoting its conversion into glycogen in the liver and muscles.
- Glucagon, produced by the pancreas, increases blood glucose levels by stimulating glycogenolysis and gluconeogenesis, releasing glucose into the bloodstream.
Energy Source for Cells
- Glucose is the primary source of energy for the body's cells, utilized to generate ATP (adenosine triphosphate) through cellular respiration.
Normal Blood Glucose Levels
- The normal range for blood glucose levels is approximately 70-100 mg/dL when fasting and up to 140 mg/dL two hours after eating.
Causes of Hypoglycemia
- Hypoglycemia can be caused by various factors including excessive insulin administration, prolonged fasting, rigorous exercise, alcohol consumption, and certain medications.
