Study Notes
Function of Insulin Hormone
- Insulin is a vital hormone that regulates the metabolism of carbohydrates, fats, and proteins in the body.
- Its primary function is to lower blood glucose levels by facilitating the uptake of glucose into cells, particularly muscle and adipose (fat) tissues.
- Insulin promotes the storage of glucose as glycogen in the liver and muscles while inhibiting the production of glucose by the liver.
Cells Producing Insulin
- Insulin is produced by beta cells located in the islets of Langerhans, which are clusters of cells in the pancreas.
- These cells respond to rising blood glucose levels by secreting insulin into the bloodstream.
Insulin's Role After Meals
- After consuming a meal, insulin levels increase to stimulate cellular uptake of glucose and store excess energy.
- It facilitates the conversion of glucose into glycogen and fat, promoting energy storage rather than usage.
Effect of Insulin on Blood Glucose Levels
- When insulin is released, it inhibits the release of glucose into the bloodstream, helping to maintain stable blood sugar levels.
- This reduction in blood glucose is crucial for preventing hyperglycemia (high blood sugar) and promoting energy utilization.
Hormones Regulating Blood Glucose
- Apart from insulin, glucagon is another key hormone produced by alpha cells of the pancreas that plays a critical role in blood glucose regulation.
- Glucagon works oppositely to insulin by raising blood glucose levels when they are low, ensuring homeostasis in energy supply.
