Flashcards in Glucose Deck (36):
ATP is how many kJ/mol?
NADH make how many kj/mol
Anaerobic metabolism of glucose makes how many ATP vs. aerobic?
Aerobic: 32 ATP
Glucose is Aldose or ketose?
Fructose is Aldose or ketose?
Galactose is Aldose or ketose?
GLUT 1 transporter is where?
GLUT-2 important for?
liver and pancreas
GLUT 4 is where?
muscle and adipose
What GLUT is key to diabetic rise in glucose? why?
decreased insulin response, GLUT 4 doesn't uptake glucose
Anaerobic glycolysis produces what?
Red Cells have mitochondria?
Red cells aerobes?
Gluconeogenesis generates glucose from?
High fructose correlated with?
Change in free energy for ATP hydrolysis?
all have in common?
NADH is storage molecule for most e- which equals?
Aldotriose vs. ketotriose?
ketotriose has C=O in middle
If too much glucose in vessels, what happens?
glycated blood vessels: prone to clots, decrease circulation
How does body deal with glucose damage?
Replace enzymes every 3 days
replace RBCs every 120 days
How does high glucose affect vision?
how to measure blood glucose on RBCs?
Body uses D or L glucose?
What is special about GLUT 4?
It migrates to cell membrane in response to insulin to allow cell uptake of glucose
does muscle have glucose-6-pase?
Nope only liver and kidney
Glycolysis makes what two energy rich molecules?
ATP and NADH
What is the Cory Cycle?
switching carbons between glycogen in muscle through lactate and back to glucose in liver
What tissues relies on anaerobic glycolysis?
3 sources for gluconeogenesis:
Are Fatty acids ketogenic or glucogenic?
What is Galactosaemia?
missing enzyme to change galactose into glucose, in infants who cannot digest mother's milk
fructose has how many carbons?
5 carbon ring, furanose
Fructose metabolism needs what?
Fructose is bad why? 2 big reasons
1. does not elicit insulin from pancreas
2. no leptin from fat cells
3. does not suppress ghrelin
