Hypo/Hyperglycemia Flashcards
(38 cards)
Normal range for blood sugar
80-120 mg/dl
what is the organ responsible for moderating blood glucose levels?
The liver
delta cells secrete
somatostatin
a cells secrete
glucagon
B cells secrete
insulin
Glucagon acts through what type of receptor?
GProtein
Insulin acts through what type of receptor?
Tyrosine kinase
3 major effects of insulin
- Decrease blood glucose levels.
- Promotes storage of fat
- Enhances protein anabolism
Type 1 diabetes is a result of
no B cells
Type 2 diabetes is a result of
insulin resistance
3 targets of insulin
Liver, Adipose, Skeletal muscle
What are the acute complications of diabetes?
Diabetic ketoacidosis, hyperosmolar hyperglycemic state, hypoglycemia
Gluconeogenesis converts what to what?
Pyruvate to glucose
pyruvate and amino acids from muscles when they are used to make energy result in
keto acid and alanine
Important intermediate in the TCA cycle (fat metabolism)
oxalacetate
What are 3 examples of ketone bodies
Acetone, acetoacetate, B-hydroxybutyrate
Acetyl CoA from B oxidation is converted to what when oxaloacetate is depleted in the TCA cycle?
Ketone bodies
Hyperosmalar hyperglycemic state most often occurs in which individuals?
Type 2 Diabetes mellitus
Hypoglycemia results usually in diabetic individuals due to?
Problems in medications-over medication/poor eating
Most chronic complications of diabetes are what type of disease?
vascular diseases
Hyperglycemia damages vessels due to what?
Reactive oxygen species-enhanced by chronic hyperglycemia
What does A1C test test for?
measures glycation of hemoglobin-allows us to measure average glucose level over a period of time. 6 or below is good.
Fasting glucose blood test measures
blood glucose level immediately-preferred test for type 1 or 2 diabetes or pre-diabetes
glucose tolerance test
measures how well your body tolerates increased glucose levels
