Answer 1

Ans.88) Option C : ABC type of pump specific to Cl^- ion

Explanation: In cystic fibrosis, CFTR (cystic fibrosis transmembrane conductance regulator gene) is affected . It codes for a membrane protein and chloride channel in vertebrates. This transmembrane protein coded by CFTR gene is a ABC transporter-class ion channel protein that conducts chloride and thiocyanate ions across epithelial cell membranes.

Ans.89) Option A : F class ATPase

Explanation: F class ATPase are known to synthesize ATP molecules by transportin H⁺ down the gradient or conduct reverse reaction of hydrolysing ATP into ADP. A class ATPase transport lipids and fats in prokaryotes.
