Fed and fasted state Flashcards
(11 cards)
First enzyme in glycolysis in pancreas
Hexokinase
Km and affinity in the pancreas
High KM and low affinity for glucose- reach Vmax at higher concentration
Liver’s form of hexokinase
Glucokinase
Enzyme that makes glycogen
Glycogen synthase
Enzyme that breaks down glucose
Glycogen phosphorylase
Which GLUT protein is insulin responsive
GLUT 4- when insulin is released you get more GLUT 4
Fitter individuals have more of which GLUT protein
GLUT 4
Key regulatory step enzyme
Phosphofruktokinase
How are pathways switched on/off
Depending on insulin or glucagon signal
VLDL use
Pack up denovo fat around the liver and ship it around the body
Occurrences in the absorptive state
Carbohydrate intake
Increased insulin and decreased glucagon
Increase in glucose breakdown, increase glycogen storage, increase glycerol synthesis
Increase TAF synthesis in adipose and liver
Increased protein synthesis
