To determine the correct answer, we need to understand what phenylketonuria (PKU) is and how it affects the body's ability to process certain nutrients.
PKU is a genetic disorder characterized by an inability to break down an amino acid called phenylalanine. Normally, our bodies convert phenylalanine into another amino acid called tyrosine, which is necessary for normal growth and development. However, individuals with PKU lack the enzyme needed to convert phenylalanine into tyrosine, leading to a buildup of phenylalanine in their blood.
Due to this metabolic issue, individuals with PKU must strictly limit their intake of phenylalanine to prevent its accumulation in the body. Therefore, the correct answer would be:
A. a specific amino acid
A person with PKU needs to leave out the specific amino acid called phenylalanine from their diet. By avoiding foods that contain phenylalanine, individuals with PKU can manage their condition and prevent the negative health effects associated with the buildup of phenylalanine in their bodies.
