Gluconeogenesis

Question 1

Whats the rate limiting step

Answer 1

Conversion of oxaloacetate to a late and back to oxaloacetate

Pyruvate to oxaloacetate: via pyruvate carboxylase
Oxaloacetate to PEP: carboxykinase

Question 2

What enzymes are not used in gluconeogenesis from glycolysis?

Answer 2

PFK > instead F16Bisphosphatase

Glucose 6 phosphatase

And enzymes that convert oxaloacetate to PEP
