Write answer in between .Q:A 3-day-old female infant presents with poor feeding, lethargy, vomiting after feeding, and seizures. Labs revealed ketoacidosis and elevated hydroxypropionic acid levels. Upon administration of parenteral glucose and protein devoid of valine, leucine, methionine, and threonine, and carnitine, the infant began to recover. Which of the following enzymes is most likely deficient in this infant?? A: Branched-chain ketoacid dehydrogenase, B: Phenylalanine hydroxylase, C: Propionyl-CoA carboxylase, D: Cystathionine synthase, E: Homogentisate oxidase,  <response>: This is a question about an infant with symptoms of poor feeding, lethargy, vomiting, seizures, and ketoacidosis along with elevated hydroxypropionic acid levels. The symptoms improved after administration of glucose, protein devoid of certain amino acids, and carnitine. The key finding is elevated hydroxypropionic acid, which indicates a defect in propionate metabolism. Propionyl-CoA carboxylase deficiency leads to accumulation of propionic acid and hydroxypropionic acid. Administration of protein devoid of valine, leucine, isoleucine, methionine and threonine which get metabolized to propionyl-CoA along with carnitine which facilitates excretion of propionyl-CoA metabolites helps treat this condition.Therefore, the enzyme deficiency is most likely propionyl-CoA carboxylase.C: Propionyl-CoA carboxylase
