hormones

1. Hormonal Regulations of
Metabolism

2. Glucagon
• Glucagon is secreted from α- cells of Pancreas
• 29 Amino Acids,
• Function of Glucagon is exact opposite of insulin (antagonist)
• Glucoagon is secreted when “GLUCOSE is GONE”
• “When Blood Glucose level is decreasing , Secretion of
glucagon will takes place
• HYPERGLYCEMIC HPORMONE”

3. ACTIONS OF GLUCAGON
• Physiological role of Glucagon is to stimulate
hepatic production and secretion of glucose
accomplishes by
 Glycogenolysis
 Increased Gluconeogenesis
– It exerts it effects on liver and adipose tissue

11. Role of Cortisol in Regulations of
Metabolism

12. • Cortisol is a steroid hormone
• Glucocorticoid class of hormones.
• Produced mainly in zona
