USMLE Step 1 - Lesson 53 - rate-determining enzymes

The rate-determining enzymes are
Glycolysis: PFK1
gluconeogenesis: fructose-1,6-bisphosphatase
TCA cycle: isocitrate dehydrogenase
Glycogenesis: glycogen synthase
Glycogenolysis glycogen phosphorylase
HMP shunt: G6PD
De novo pyrimidine synthesis: carbamoyl phosphate synthetase 2
De novo purine synthesis: glutamine-PRPP-amidotransferase
Urea cycle: carbamoyl phosphate synthetase 1
Fatty acid synthesis: ACC
Fatty acid oxidation: carnitine acyltransferase 1
Ketogenesis: HMG-CoA synthase
Cholesterol synthesis: HMG-CoA reductase

Awesome videos. thank you very much. Isocitrate dehydrogenase catalyzes the conversion of isocitrate to a-ketoglutarate, not the other way around.

Please sir is a rate determining enzyme the enzyme that catalyzes the rate determining step?? Is a rate determining enzyme same as a regulatory enzyme??

These give me hard times
