Glucagon is made by

α cells of pancreas

2

glucagon function

catabolic effect
a. glyconeogenolysis
b, glyconeogenesesis
c. lipolysis
d. ketone production

3

regulation

- secreted in response to hypoglycemia
-inhibited by INSULIN, HYPERGLYCEMIA, SOMATOSTATIN

4

glycagon secretion is inhibited by

INSULIN,
HYPERGLYCEMIA,
SOMATOSTATIN

5

You study 12 hours without food. Hypoglycemia induces which cells to produce glucagon? Which hormones inhibit glucagon production?

α cells of the pancreas; insulin, hyperglycemia, and somatostatin inhibit glucagon production

6

In general, glucagon is a catabolic hormone. As such, which metabolic pathways does it induce?

Glycogenolysis, gluconeogenesis, lipolysis, ketone production

7

A patient is taking octreotide (somatostatin analog) for acromegaly. What effect will this drug have on his glucagon secretion?

Will inhibit glucagon secretion
