fructose 1,6 phosphate
shuts down gluconeo when F6P or F26P concentrations rise
What two enzymes begin the process of breaking down glucose?
hexokinase in muscle and glucokinase in liver
What other sugar can hexokinase work on?
d-fructose from diet-->F-6-P in glycolysis lineup
What enyzme splits fructose 1,6 bisphosphate into glyceraldehyde-3-phosphate?
aldolase A or B
What byproduct is created when alanine is converted to pyruvate?
What is THE rate limiting enzyme in glycolysis?
What inhibits PFK function?
ATP and citrate
fatty acids, ketone bodies, glucagon, cAMP
What induces PFK?
What activates PFK?
AMP, F6P, Pi, F2,6bisP
What's the ATP breakeven point in glycolysis?
What enzyme converts PEP to pyruvate?
What enzyme converts pyruvate to acetyl-CoA?
What are the 3 top substrates for gluconeogenesis?
alanine, lactate, glycerol
What four enzymes are key in gluconeogenesis?
py box, py box kin, f-1,6 diP, glu-6P
Which one of those enyzmes converts oxaloacetate to PEP?
Which one converst pyruvate to oxaloacetate?
Which one converts F-1,6-P to F-6-P?
Which one makes glucose from G6P?
What enzyme interconverts pyruvate and lactate?
LDH, I think that's lactate dehydrogenase
Which member of the TCA cycle can cross the mitochondrial membrane?
What is formed by fatty acid breakdown that can join the TCA cycle?
