dominant hormone when blood glucose level is high. Stores energy- binding to receptor sites , changing the permeability of the membrane such that glucose enters the cell more readily.

"Transports Glucose"

• Dominate hormone when blood glucose is low
• produces energy
• acts on liver to increase glycogenolysis ( conversion of glycogen into glucose)
• in extreme cases= Gluconeogenesis ( break down of protein and fat into glucose)

• Alpha: Produces glucogon
• Beta: produces Insulin
• Delta: Somastatin ( inhibits glucogon and insulin)

• very low production of insulin by the pancreas
• require insulin injections
• heredity is a factor for determining who will be predisposed to type 1

• moderate devline in insulin production
• increased weight (increased size of fat cells) causes a relative deficiency in the number of insulin receptors per cell, making fat less responsive to insulin
• more common

What is the emergency?
Signs and symtoms:

• Polyuria, polydipsia, polyphagia
• warm, dry skin
• N/V
• Kussmauls resps
• fruity odor on breath
• tachycardia

• complication of type 1 diabetes
• profound insulin deficiency with increased glucagon activity
• body uses gluconeogensis- creates ketones
• changing the Ph to more acidic
