|
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 |
