Question

Quizplus · Accepted Answer

The amino acid glutamine is the source of nitrogen for the synthesis of glucosamine-6-phosphate from fructose-6-phosphate. Glutamine undergoes a reaction with fructose-6-phosphate catalyzed by the enzyme glutamine:fructose-6-phosphate amidotransferase, which results in the formation of glucosamine-6-phosphate and glutamate. Therefore, choice D (glutamine) is the correct answer.
