The Fed and the Fasting States Flashcards
can glucose be made from fat
NO
what are the fuels used in the liver during the fed state
dietary amino acids and carbohydrates
what are the fuesl used in early fasting in the liver
adupose fatty acids
what are the fuels used during 24 hour fasting in the liver
adipose fatty acids
what are the fuels used during starvation in the liver
adipose fatty acids
RBC’s use what fuels during fed, early fasting 24 hour fasting and starvation
blood glucose
brain uses what fuels during fed, early fasting and 24 hour fasting
blood glucose
brain uses what fuels during starvation
ketone bodies and blood glucose
adipose tissue uses what fuels during fed state
blood glucose
adipose tissue uses what fuels druing early fasting
fatty acids and ketone bodies
adipose tissue uses what fuels druing 24 hour fasting
fatty acids and ketone bodies
starvation adipose tissue
fatty acid and ketone bodies
cardiac muscle and skeletal muscle use what during fed state
blood glucose, FA, and fatty acids synthesized by the liver
early fasting muscle
blood glucose little, adpose and heart /muscle amino acids
24 hour fasting muscle
blood glucose, adipose fatty acids and amino acids
starvation muscle
adipose FAand ketone bodies
function of alpha amylase
hydrolyzes alpha 1,4 bonds between glucosyl residues and forms alpha dextrans
function of salivary amylase
forms alpha dextrans
disaccharideases
breaks down alpha dextrans and dietary disaccharides, found in intestine
what is responsible for raises the pH to allow the pancreatic enzymes to function
bicarbonate
_____-breaks triacylglyceroal into 2 MAG and fatty acids
pancreatic lipase
________binds fat and activates pancreatic lipase
colipase
pancreatic lipase needs what additiona enzyme for digestion of fats
colipase
what is the function of apoproteins
recognized by lipoprotein lipase
insulin is produced by
beta cells of pancreas
glucagon is produced by
alpha cells of pancreas
in the fed state there is an increase in
glucokinase, glycogen synthase, pyruvate kinase, G6p dehydrogenase, acetyl coA carboxylase and fatty acid synthase
lipoolysis is incread by
glucagon
lipolysisi is decreass by
insuiln
does the liver store triacylglycerol
NO
adipose uses glucose for
the glycoerl part of triacyglycerol synthesis
glucose levels are max
at 60 min post meal
fasting levels of glucose are
2 hours post meal
glucagon starts to increase as insulin and glucose begin to
decrease
low insulin levels in adipose stimulate
triacylglycerol breakdown
the liver produces ________fro FA
ketone bodies
in prolonged starvationthe brain can use
ketone bodies
gluconeogenesis occur in the
liver
in prolonged fasting what happens to the level of muscle degradation
less muscle protein is degraded
what becomes the major fuel store in starvation
fat
in type 1 diabetes, it is similar to always being in
fasting state
shrot term for maintaining blood glucose is
glycogen
long term for mainaining blood glucose is
amino acids, glycerol and lactate
what would be elevated after a 24 hour fast
fatty acids and urea
what would be elevated after a 72 hour fast
ketone bodies
