Final answer:
The student's question asks for the end products when modifications are made to the amino acid glutamine. Swapping out an N for an O through transamination and removing the N in the backbone both actually lead to the production of glutamate. The options provided do not accurately represent these biochemical processes.
Step-by-step explanation:
If we swap out an N for an O in glutamine via transamination, we get glutamate. If we remove the N in the backbone, we get glutamate again, as this is a process of oxidative deamination. Therefore, the correct answers are not found in the options provided. In transamination, the amino group of an amino acid is typically exchanged with the keto group of an alpha-keto acid. This exchange can convert glutamine into glutamate, as the amino group is transferred. Oxidative deamination involves the removal of an amino group from glutamate, typically forming an ammonium ion and leaving behind alpha-ketoglutarate.
Alanine and aspartate mentioned in the background information are relevant in the context of transamination, where the former can be produced by transferring an amino group from a glutamate to pyruvate, and the latter from glutamate to oxaloacetate. Similarly, asparagine can be synthetized by transferring the amino group from glutamine to aspartate.
