One type of mutation in the CFTR protein prevents the transport of chloride ions through the channel. What is most likely to be observed in the lungs of patients with this mutation?A. Dehydrated epithelial cellsB. Dehydrated mucusC. Mucus with excess waterD. Mucus with a high electrolyte concentration

What effect does a faulty CF gene have in the lungs?Group of answer choicesThe production of thick mucous that "clogs" the lungsA reduction in the occurrence of respiratory infectionsThe lungs are unaffected when the CF gene is faultyA lack of digestive enzyme secretions

A human genetic disorder caused by a recessive allele for a chloride channel protein; characterized by an excessive secretion of mucus and consequent vulnerability to infection; fatal if untreated.Group of answer choicesTay-Sachs diseasesickle-cell diseaseHuntington’s diseasecystic fibrosisNext

The major role of the protein encoded by the CF gene is to control the transport of which two ions?Group of answer choicesSodium (Na+) and Chloride (Cl-)Chloride (Cl-) and Potassium (K+)Potassium (K+) and Sodium (Na+)Water (H20) and Sodium (Na+)

The disease cystic fibrosis causes a variety of phenotypic effects. The lack of a functional chloride ion transporter leads to a buildup of sticky mucus in the lungs. The same deficit causes production of salty sweat because skin cells cannot recover salts that have entered the sweat glands. An explanation for why these two different effects can be caused by the same gene is that the cystic fibrosis gene is expressed in ______.Multiple choice question.lung cells but not skin cellsboth lung cells and skin cellsskin cells but not lung cells

Which of these signs, symptoms and pathological hallmarks is attributed to the correct disease?Question 1Answera.Excess chloride ion excretion from cells and thin, watery mucus in lungs - CYSTIC FIBROSIS.b.Increased respiratory rate and reduced CO2 in blood - CHRONIC BRONCHITIS.c.Metaplasia of epithelial cells in the bronchi - PNEUMONIA.d.Increased protease and reduced anti-protease activity in alveoli - EMPHYSEMA.e.Reduced inflammation in lungs, no alveolar wall damage and high blood O2 saturation - COVID-19.
