16.3 Hormones and the regulation of blood glucose concentration

Hormones are:

Second messenger model: Involving adrenaline

The cells of the islets of Langerhans include:

The role of the liver in regulating blood sugar:

Regulation of blood glucose concentration

Factors that influence bloog glucose concentration: Blood comes from three sources:

Which hormones operate to maintain a constant blood glucose concentration:

• Insulin

• Glucagon

• Adrenaline

Introduction to insulin and the Beta cells of the pancreas:

Almost all body cells have glycoprotein receptors on their cell-surface membranes that bind specifically with insulin molecules. When it combines with the receptors, insulin brings about:

Blood glucose concentration is lowered in one or more of the following ways:

Glucagon and the alpha cells of the pancreas:

Adrenaline raises the blood glucose concentration by:
