The first Step of Gluconeogenesis is Conversion of pyruvate to Phosphoenol Pyruvate PEP.
This requires the action of 2 Mitochondrial Enzymes:
The first is an ATP requiring reaction catalysed by pyruvate Carboxylase PC.
Pyruvate is carboxylated to form Oxalacetate OAA. .
The second Enzyme in the conversion of pyruvate to PEP is: PEP carboxykinase PEPCK.
PEPCK requires GTP in the decarboxylation of OAA to yield to PEP.

In the first step of gluconeogenesis, pyruvate is converted into phosphoenol pyruvate then why the correct option is C (Oxaloacetate)?

Why its answer is oxaloacetate, not Acetyl CoA?
Please discuss accordingly with logical reasons.
