2) Write the reaction for transfer of the N from the amino acid aspartate to the a-ketoacid a-ketoglutarate and the new products that are formed. Indicate the functional groups that are changed. What is the name of the amino acid produced in the above reaction that results when the aspartic acid has its NH3 transferred to a-ketoglutarate? Likewise what does aspartic acid become?

2) Write the reaction for transfer of the N from the amino
acid aspartate to the a-ketoacid a-ketoglutarate and the
new products that are formed. Indicate the functional
groups that are changed. What is the name of the amino
acid produced in the above reaction that results when the
aspartic acid has its NH3 transferred to a-ketoglutarate?
Likewise what does aspartic acid become?
3) What is the utility of the reaction in question 2 in terms
of nitrogen catabolism?
4) The glutamate that is made in question 2 is converted
back to a-ketoglutarate as part of nitrogen catabolism.
What is the name of the enzyme that restores a-
ketoglutarate from glutamate. What type of reaction is
this?
