Question

Quizplus · Accepted Answer

Ammonia can be incorporated into glutamate most directly through the process of transamination, which transfers an amino group from an amino acid (such as alanine or aspartate) to α-ketoglutarate to form glutamate. This process requires the action of the enzyme glutamate dehydrogenase, which is activated by high levels of ammonia. Glutamate can then be further metabolized in the urea cycle to eliminate excess ammonia from the body. Choices A, C, D, and E are not as directly involved in ammonia metabolism as glutamate.
