carbohydrates Flashcards
is both an endocrine and exocrine organ in the control of carbohydrate metabolism
a. pancreas
b. insulin
c. glucagon
pancrease
- both endocrine and exocrine
produces and secretes an amylase responsible for the breakdown of ingested complex carbohydrates
a. endocrine gland
b. exocrine glan
pancreas
- both an endo and exocrine organ
endocrine gland
- secretes the HORMONES, INSULIN , AND SOMATOSTATIN from different cells residing in the islet of Langerhans in the pancreas
exocrine gland
- produce and secrete an amylase responsible for the breakdown of ingested complex carbohydrates
insulin are released when glucose are ___
a. high
b. low
insulin is normally released when glucose are HIGH
glucagon is released during STRESS AND FASTING STATES
hypoglycemic agent - only hormone that decreases glucose levels
a. insulin
b. glucagon
insulin
- normally released when glucose are high
- only hormone that DECREASES GLUCOSE LEVELS - hypoglycemic agent
serum insulin measurements may be ___________ in the presence of hemolysis
a. falsely high
b. falsely low
serum insulin measurements may be FALSELY LOW in the presence of hemolysis
hyperglycemic agent
a. pancreas
b. insulin
c. glucagon
glucagon
- primary hormone responsible for INCREASING GLUCOSE - hyperglycemic agent
- alpha cells of the islet of langerhans
- released during stess and fasting states
- fasting plasma glucagon conc are normally 25-50pg/mL
hormones that secreted by the anterior pituitary gland
a. cortisol and corticosteroid’
b. cathecolamines
c. growth hormone
d. somatostatin
growth hormone
- secreted by the ANTERIOR PITUITARY GLAND
stimulates the release of cortisol from adrenal cortex
a. cortisol and corticosteroid’
b. cathecolamines
c. growth hormone
d. somatostatin
adrenocorticotropic hormone
release of cortisol fr0m adrenal cortex
promotes glycogenolysis, glycolysis
a. cathecolamines
b. growth hormone
c. ACTH
d. thyroid hormones
Catecholamines
- promotes glycogenolysis, and lipolysis
growth hormone
- glycogenolysos, glycolysis
(GGG)
ACTH
- promotes gylcogenolysis and gluconeogenis
th
- promotes glycogenolysis, gluconeogenesis and intestinal absorption og glucose
in iron deficiency anemia what is the result of hba1c
a. low
b. high
older rbc and IDA may have HIGH HBA1C LEVELS
what test is useful in patient monitoring diabetic individuals with chronic hemolytic anemia and HbS / Hbn
a. Hba1c
b. fructosamine
c, ogtt
fructosamine/ glycosylated or glycated albumin
- it is reflection of short term glucose control (2-3 weeks)
- useful in patient monitoring diabetic individuals with chronic hemolytic anemia and HbS / Hbn - decrease lifespan
