Question

Cystic fibrosis is caused by a mutated gene that produces a defective enzyme in the secretory cells. Which statement CORRECTLY describes its treatment interventions? A) regular exercise to control blood cholesterol B) use of vaccines to increase the number of T helper cells C) insulin injections to help transport sugar out of the blood D) antibiotics to cure lung damage caused by thick mucus infection

Answer 1

Answer:

D

Explanation:

This mutation affects these secretory cells and causes them to secrete a thick secretion (rather than the normal 'thin' kind) hence they clog up ducts, pores, and tubes. This is how even the lungs are affected causing wheezing and breathlessness. It gest worse when the mucus accumulates infectious bacteria.
