Cystic fibrosis is a genetic condition that is associated with defects in the CFTR protein. The CFTR protein is a gated ion channel that requires ATP binding in order to allow chloride ions (CI-) to diffuse across the membrane.
In the provided model of a cell, draw arrows to describe the pathway for production of a normal CFTR protein from gene expression to final cellular location.
Identify the most likely cellular location of the ribosomes that synthesize CFTR protein.
Identify the most likely cellular location of a mutant CFTR protein that has an amino acid substitution in the ATP-binding site.
