Pancreas and Hormones Flashcards
Major regulatory organ of glucose (both an exocrine & endocrine)
Pancreas
The exocrine gland produce and secretes
Amylase
Breaks down polysaccharide by destroying the glycosidic linkages
Amylase
Considered as the smallest enzyme enabling it to pass through the glomerulus to be NORMALLY excreted in the urine
Amylase
the EARLIEST pancreatic marker
Amylase
Isoenzyme of amylase produced by salivary gland
S-type (Ptyalin)
Isoenzyme of amylase produced by the acinar cells of pancrease
P-type (Amylopsin)
The endocrine gland secretes
Insulin (beta cells)
Glucagon (Alpha)
Somatostatin (delta cells of Langerhans)
Insulin, glucagon and somatostatin are produced by the
Pancreas (Islet of Langerhans)
Primary hormone responsible for the
entry of glucose into the cell (liver,
muscle, & adipose tissue) This action is done by enhancing the permeability of the cell to glucose
Insulin
Insulin promotes
Glycogenesis, Lipogenesis, & Glycolysis
Insulin decreases
Glycogenolysis
T/F: Serum Insulin: sample must be free from
hemolysis to prevent falsely decreased
result (due to the presence of Insulin Degrading Enzymes in RBC)
TRUE
Effects of insulin in glucose
Decrease
PRIMARY Hyperglycemic agent
Prevents cellular uptake of glucose
(prevents entry of glucose in contrast
with insulin)
Glucagon
