Carbs II Flashcards
General outline of glycolysis
covert glucose to 2 molecules of pyruvate, yeiling 2 molecules of ATP and reduced NADH
what can happen to pyruvate
gets fermented into lactate or ethanol, or oxidaized
what do RBC rely on
exclusively on glycolysis
what do brain cells rely on
mostly glucose (fatty acids can’t cross bbb)
is glycolysis an anaerobic or aerobic reaction
anaerobic
1st stage of glycolysis
glucose phosphoryalted twice, yeidls fructose 1, 6 bisphophaste. requires 2 ATP
2nd stage of glycolysis
fructose 1,6 bisphophase split into 2 fragements
3rd stage of glycolysis
, gives 2 ATP
how is fructose procesed
fructokinase in liver
hexokinase in muscle
is teh fructokianse reaction dependent on insulin
no
how do you degrade galactose
phosphoryalted, link to UDP. UDP galactose transported into UDP glucose
what is essential fructosuria caused by
deficieny of liver fructokinase
what is hereditary fructose intolerance casued by
deficency in aldolase B
symptoms of hereditary fructose intoleracnce
jaundice, kidney failure
how do you treat hereditary fructose intoelranc
fructose free diet
