help with filling in the blanks   The amino acid [alanine/aspartate/glutamate] can be transaminated to a- ketoglutarate, the amino acid [alanine/aspartate/glutamate] can be transaminated to pyruvate, and the amino acid [alanine/aspartate/glutamate] can be transaminated to oxaloacetate. As a result, all three amino acids are considered [glucogenic/ketogenic/metagenic].   The carbon of urea comes directly from [carbon dioxide/a-carbon of an amino acid/glucose]. The nitrogen atoms in urea come from [ammonia/DNA/pyruvate] and [aspartate/glutamate/alanine] directly.
