What is the primary function of the enzyme Pyruvate Carboxylase in protein metabolism?

A To catalyze the conversion of pyruvate to oxaloacetate ✓
B To catalyze the conversion of oxaloacetate to pyruvate
C To catalyze the conversion of alanine to pyruvate
D To catalyze the conversion of glutamate to alpha-ketoglutarate

Explanation

Pyruvate Carboxylase is an enzyme that plays a crucial role in protein metabolism by catalyzing the conversion of pyruvate to oxaloacetate, which is then used for gluconeogenesis or as a precursor for amino acid synthesis.
