Study Notes
Insulin and Glucose Regulation
- The primary function of insulin is to regulate blood glucose levels by facilitating glucose uptake in cells.
- Insulin stimulates glucose uptake in muscle cells by triggering the translocation of glucose transporter proteins to the cell surface, increasing glucose absorption.
- Insulin is produced by beta cells in the islets of Langerhans within the pancreas in the human body.
- Diabetes is a condition characterized by high blood glucose levels due to inadequate insulin production or insulin resistance, leading to impaired glucose regulation.
- Insulin resistance is a term describing the decreased response of cells to insulin, leading to high blood glucose levels as glucose builds up in the blood instead of being absorbed by cells.
