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  
🗑
