Answer:
The answers A, B and C are correct
Explanation:
- Gluconeogenesis primarily occurs in the mitochondria mainly in the liver.
- Oxaloacetate is used to generate PEP by a two step process.
1) conversion of Pyruvate to oxaloacetate catalyzed by pyruvate carboxylase. This process requires ATP hydrolysis.
2) The decarboxylation and phosphorylation of oxaloacetate catalyzed by phosphoenolpyruvate carboxykinase (PEPCK) producing PEP. This process requires the hydrolysis of GTP.
Therefore options A, B and C are correct.
