Question | Answer |
---|---|
hexokinase | 1st phosphorylation of glycolysis |
glucose 6 phosphatase | opposite of hexokinase reaction but in gluconeogenesis. Def = Von Gierke's |
G-6-P dehydrogenase | takes G6P into HMP shunt |
transketolase | brings back R5P to glycolytic pathway from HMP shunt as F6P |
PFK | Rate limiting of glycolysis, adds 2nd phosphate to glucose to make F1,6,BP |
Aldolase | breaks F16BP to 2-3 carbon molecules, glyceraldehyde and HDAP. |
Pyruvate kinase | Removes the last phosphate from PEP to make pyruvate |
pyruvate dehydrogenase | makes acetyl-coa from pyruvate to go into TCA |
pyruvate carboxylase | makes oxaloacetate directly from pyruvate, part of gluconeogenesis |
PEP carboxykinase | takes oxaloacetate back up skipping pyruvate and going directly to PEP for gluconeogenesis |
citrate synthase | 1st step in tca. makes citrate from acetyl coa and oxaloacetate |
ornithine transcarbamylase | 1st part of urea cycle. ornithine + carbamoyl phosphate = citrullline. |
HMG coa reductase | rate limiting of cholesterol synth |
alpha ketoglutarate dehydrogenase | makes succinyl coa from alpha keto glut |
