Fuel Utilization Flashcards
What blood glucose levels are necessary for organ function
between 90-100 mg/dl
What is the primary contributor to blood glucose
liver
What is glucose stored as if it is not used right away
stored fat, liver glycogen
can amino acids be stored as fat?
yes
What are glycerol and fatty acids stored as
triglycerides
how does glucose enter the working cell?
Facilitative glucose transporters for facilitative diffusion into cells
GLUT 1 & GLUT 4
High blood sugar in an absorptive state promotes what to be released from pancreas
insulin
What does insulin stimulate in the liver
stops glycogeneolysis, and stimulates glycogen production
When insulin molecule binds to its receptor, what happens
GLUT 4 goes to cell membrane and communicates “go ahead and come in the cell glucose”
What besides insulin attachment activates the glucose transport into the cell by sending GLUT 4 to the cell membrane
exercise
When does glycogenolysis occur
post absorptive state (4+ hours resting metabolism)
What does pancreas release in a low absorptive state
glucagon
what does glucagon stimulate in the liver
glycogen breakdown
Low to moderate intensity, our body uses
fats
an increase of Norepinephrine and Epinephrine stimulates____ and inhibits____
glucagon, insulin
