Glucose Homeostasis Flashcards
(32 cards)
Alpha cells pancreas respond to what
Hypoglycemia only
Alpha cells pancreas release what hormone
Glucagon
Alpha cells pancreas target what organ
Liver and Adipose
When Alpha cell target the Liver, what pathway is increases?
Glycogenolysis
Gluconeogenesis
Beta Oxidation of fats termed
Ketogenesis
When Alpha cell target the Adipose, what pathway is increased?
Lipolysis
The hypothalamus responds to what
Hypoglycaemia PLUS exercise or sleep
The hypothalamus releases what hormone
Growth Hormone
When the hypothalamus targets the Liver, what pathway is increased?
GH is converted to Insulin like Growth Factor 1 AKA Somatomedin C
When the hypothalamus targets the muscle, what pathway is increased?
Increases
-Amino acid uptake
-proteins synthesis
-beta oxidation fats
When the hypothalamus targets the muscle, what pathway is Decreased?
Decreases:
Protein Breakdown
Carbohydrate
Metabolism
The hypothalamus target what organs
-Liver
-muscle responds to somatomedian C and growth hormone
Adrenal medulla responds to what
Hypoglycemia PLUS acute stress
What happens when you wake up stressed
You become hypoglycaemic which causes your body to make epinephrine
What hormone is released in the Adrenal medulla
Epinephrine
The adrenal medulla targets what organs?
Liver
Adipose
Muscle
The adrenal medulla and cortex targets the liver which increases what pathway?
Glycogenolysis
Gluconeogenesis
Beta oxidation of fats termed Ketogenesis
The adrenal medulla targets the Muscle which increases what pathway?
Glycogenolysis
krebs Cycle
Beta oxidation of fats
The adrenal medulla and cortex targets the Adipose which increases what pathway?
Lipolysis
The adrenal cortex targets the Muscle which increases what pathway?
Blocks the Glut 4 transporter
Adrenal cortex targets what organs
Liver
Muscle
Adipose
Adrenal cortex responds to what
Chronic stress and does not need hypoglycaemia to be released
The adrenal cortex releases what hormone?
Cortisol
Beta cells pancreas responds to what?
Hyperglycaemia
Beta cells pancreas release what hormone?
Insulin
