Cystic fibrosis has an abnormal CFTR transport protein that limits water transport out of the cells and the body.

A) Cholera toxin inhibits CFTR leading to decreased transport of water into the intestines.
B) Cholera toxin inhibits CFTR leading to increased transport of water into the intestines.
C) Cholera toxin stimulates CFTR leading to decreased transport of water into the intestines.
D) Cholera toxin stimulates CFTR leading to increased transport of water into the intestines.
E) Cholera toxin causes a DNA genetic mutation that modifies the function of CFTR proteins.
