Question

cystic fibrosis is a genetic disorder in humans that results in the overproduction of thick mucous in the small intestines that results in malnutrition. what is the explanation for this? the mucous prevents the production of atp by the mitochondria which is needed for nutrient absorption. the mucous forms a barrier around the cell wall and nutrients cannot be absorbed. the mucous blocks the microvilli of the plasma membrane and nutrient absorption cannot occur. the mucous blocks the peptidoglycan and nutrients cannot be absorbed.

Explanation:

Cystic fibrosis causes over - production of thick mucus in the small intestine. This mucus blocks the microvilli of the plasma membrane, hindering nutrient absorption. It does not directly affect peptidoglycan, form a barrier around the cell wall, or prevent ATP production by mitochondria for nutrient absorption.

Answer:

The mucus blocks the microvilli of the plasma membrane and nutrient absorption cannot occur.
