Which of the following enzyme is not present in the skeletal muscles?
A. Creatinine phosphokinaseB. Hexokinase
C. Phosphofructokinase
D. Glucose-6-phosphatase
Ans.
D. Glucose-6-phosphatase.
Glucose-6-phosphatase enzyme is not present in the skeletal muscles; therefore, the end product ofgluconeogenesis in skeleton muscles is glucose-6-phosphate, not glucose.
Key enzymes of gluconeogenesis are:-
•Glucose-6-phosphatase.
• Fructose 1, 6—biphosphatase.
• Phosphoenolpyruvate carboxykinase.
• Pyruvate carboxylase.
All the four enzymes are present in liver and kidney only
