The degradation of arginine,histidine and proline all lead to the product ________.

Question

Quizplus · Accepted Answer

The degradation of arginine, histidine, and proline leads to the production of glutamate through different pathways. Arginine is degraded into ornithine and urea, followed by the conversion of ornithine into glutamate, while histidine is converted into glutamate via intermediates such as urocanate and imidazolone-5-proprionic acid. Proline is metabolized to glutamate through a two-step process involving the intermediate pyrroline-5-carboxylate. Therefore, the correct answer is D, glutamate. Neither pyruvate, acetyl CoA nor acetoacetate is a product of the degradation of these amino acids.
