Question

A child with cystic fibrosis has a mutated protein in his cells which does not behave normally. The mutated protein stops chloride ions from leaving the cells. This causes water to be retained in the cell creating thicker fluids. These fluids cause a buildup of mucus which leads to breathing problems.

Which cell structure is most likely being negatively affected by the mutated protein?


A.The mutated protein is most affecting the cell membrane because the protein is causing water to be stored in the cell and water storage is a function of the cell membrane.


B.The mutated protein is most affecting the nucleus because the protein is preventing DNA production which is a function of the nucleus.


C.The mutated protein is most affecting the cell membrane because the protein is not allowing certain materials to leave the cell, which is a function of the cell membrane.


D.The mutated protein is most affecting the ribosomes because the protein is causing the production of excess mucus which is a function of the ribosomes.
