Garrod's information about the enzyme alteration resulting in alkaptonuria led to further elucidation of the same pathway in humans. Phenylketonuria (PKU) occurs when another enzyme in the pathway is altered or missing, resulting in a failure of phenylalanine (phe) to be metabolized to another amino acid: tyrosine. Tyrosine is an earlier substrate in the pathway altered in alkaptonuria. How might PKU affect the presence or absence of alkaptonuria?

In the presence or absence of alkaptonuria the phenylketonuria (PKU) would have no effect because tyrosine is also available from the dietary supplement.

there should be recorded video of the class under the assignments for the day

was there more to the question like a picture or something? also i mean with no picture i think something that's not likely to be an educational impact would probably be the way the child is raised since it has special health care needs
