Gluconeogenesis at a glance

 Substrate :http://medicalscienceeasy.blogspot.com/2017/12/substrstes-of-gluconeogenesis-at-glance.html

Site: liver 90% , Kidney 10%
Compartment: Mainly cytoplasm ,party in mitochondria
Nature : Anabolic
Rate limiting enzyme http://medicalscienceeasy.blogspot.com/2017/12/rate-limiting-enzymes-of-gluconeogenesis.html
 ATP needed: 6 ( to produce 1 glucose from substrate)
Source of ATP : Beta Oxydation of fatty acid
 Importance:

  • Maintain normal glucose concentration in fasting & starvation
  • Disposal of lactic acid & glycerol in normal state

Factors regulate Gluconeogenesis


Factors increase / stimulate Gluconeogenesis :

  • ATP
  • Acetyl CoA
  • Cortisol
  • Epinephrine
  • NADH
  • Glucagone

Factors decrease / inhabit Gluconeogenesis :

  • AMP
  • Fructose -2,6- Bis Phosphate
  • Insulin

Rate limiting enzymes of Gluconeogenesis




  •  Pyruvate carboxylase
    • Pyruvate to Oxaloacetate

  • Phosphoenol pyruvate carboxykinase

    • Oxaloacetate to Phosphoenol pyruvate

  • Fructose -1,6- bis phosphatase

    • Fructose -1,6- bis phosphate to  Glucose-6- phosphate
  • Glucose Bis phosphatase
    • Glucose-6- phosphate to Glucose
