Glycogenesis

Question 15

Glucose –Insulin Glycogen

Answer 15

Glycogenesis

Question 16

Breakdown of glycogen to G-6-P

Glycogen –Glucagon Glucose

Answer 16

Glycogenolysis

Question 17

Insulin (Hypoglycemic agent)

Answer 17

decreasing ↓ glucose
syn from the β cells of the islets of Langerhan
↑ glycogenesis, glycolysis, lipogenesis; and ↓ glycogenolysis.

Question 18

Glucagon (hyperglycemic agent)

Answer 18

Primary hormone responsible increasing blood glucose
Synthesized by the α cells of the islets of Langerhan (pancreas)
↑ glycogenolysis and gluconeogenesis.

Question 19

Epinephrine

Answer 19

Produced by the adrenal medulla, ↑ blood glucose
Released during times of physical and emotional stress
Inhibits insulin secretion, ↑ glycogenolysis and lipolysis

Question 20

Cortisol

Answer 20

Produced by the adrenal cortex, ↑ plasma glucose

↓ intestinal entry of glucose into the cell, ↑ gluconeogenesis, glycogenolysis and lipolysis

Question 21

Growth hormone

Answer 21

Produced by the anterior pituitary gland; ↑ plasma glucose

↓ glucose entry to cells, ↑ glycolysis

Question 22

Thyroxine

Answer 22

Produced by the thyroid gland; ↑ plasma glucose

↑ glycogenolysis, gluconeogenesis and glucose intestinal absorption

Question 23

Somastostatin

Answer 23

Produced by the Delta cells of the islet of Langerhans in the pancreas and hypothalamus
↑ plasma glucose by inhibition of insulin, glucagon, GH, etc.

Question 24

Answer 24

Diabetes Mellitus

Answer 26

Type 1 (IDDM)

Question 27

Adult onset

90% of all cases of diabetes

Answer 27

Type 2 (NIDDM)

Question 28

Relative insulin deficiency
↑ with age, obesity and lack of exercise
Insulin is present (hyperinsulinemia)
Glucagon secretion is attenuated

Answer 28

Type 2 (NIDDM)

Type 2 (NIDDM)

Non Insulin dependent
Ketosis tendency is seldom
Greater tendency to develop hyperosmolar states
Polydipsia, Polyphagia, Polyuria
