Question

multiple choice 2.5 points people with sickle-cell disease have abnormal phenylalanine hydrolyase activity. tumor suppressor function. cholesterol transport function. hemoglobin function. glucose metabolism.

Explanation:

Sickle - cell disease is a genetic disorder that affects the structure of hemoglobin. Hemoglobin is the protein in red blood cells that carries oxygen. In sickle - cell disease, the hemoglobin (specifically hemoglobin S) has an abnormal structure, which leads to abnormal hemoglobin function. Phenylalanine hydrolyase is related to phenylketonuria, tumor suppressor function is related to cancer - related genes, cholesterol transport function is related to lipid metabolism and related proteins, and glucose metabolism is related to enzymes and processes involved in glucose breakdown or synthesis. So the correct option is the one related to hemoglobin function.

Answer:

D. hemoglobin function.
