a) The mitochondria are defective and do not produce sufficient protein to synthesize microtubules in the cilia and flagella. b) The plasma membrane of the alveoli is not permeable to carbon dioxide during respiration because it is too hydrophobic. c) The Golgi bodies secrete an enzyme that destroys the proteins in the flagella and cilia. d) The cells do not produce functional motor proteins in flagella and cilia.
