fed
w/in 24 hours of a meal
fasting
2-4 hours after meal
-basal rate = 12 hours
starved
3-5 days fasting
after meal: glucagon? insulin?
glucagon: low
insulin: high
carbs in fed state storage
-glycogen: liver/skeletal muscles
-fat
AA from protein
-energy to TCA cycle
-synt new pro
-compds from AA
glycogen in fasting state
-breakdown from liver to maintain BG
-liver holds about 300g glycogen
-skeletal muscle glycogen cant contribute to BG
fats/proteins in fasting state
TG preferred over protein
-accessed when glycogen stores drop
fats in fasting state
-FA undergo beta-oxidation to feed TCA cycle
-lipases break down TG to glycerol + FA
gluconeogenesis
-synth glu from TG and pro
-occurs in liver
ketone bodies
-product beta-oxidation
-alt source of E
Cori cycle
lactate used as substrate to produce glu via gluconeogenesis
fasting -> starvation
brain?
muscle?
liver?
-muscle: dec. use of KB, dec pro degradation
-liver: dec gluconeogenesis; dec urea production
-brain: inc use of KB; dec use glu
