Question

What are the rate limiting enzymes for glycolysis, fermentation, glycogenesis, glycogenolysis, gluconeogenesis, and pentose phosphate pathway?

Answer 1

Rate-limiting enzymes are key enzymes that determine the overall rate of a metabolic pathway. Here are the rate-limiting enzymes for the pathways you mentioned:

Glycolysis: Phosphofructokinase

Gluconeogenesis: PEP (phosphoenol pyruvate) carboxylase

Glycogenesis: Glycogen synthase

Glycogenolysis: Glycogen phosphorylase
