Cells of the digestive tract that secretes digestive enzymes, produce and package vacuoles of digestive enzymes for secretion into the small intestines. What cell organelle would fit this function?

• cell wall

• ribosome

• vacuole

• golgi

Read through the following situations and identify the organelle malfunctioning or primarily affected in individuals with each disorder.

• cell membrane

• Achondrogenesis: Infant has a small body, short limbs and other skeletal abnormalities. Due to serious health problems infants are stillborn or die soon after birth. ABNORMALITIES ARE DUE TO PROTEINS NOT BEING PACKAGED AND MOVED.

• mitochondria

• Leigh’s Disease: Infants with the syndrome have trouble swallowing, leading to a failure to thrive. This usually occurs after a viral infection. They also become irritable and cry continuously. ORGANS THAT NEED A LOT OF ENERGY like the brain, heart, and intestines WILL BE AFFECTED. Lesions on the brain and brain stem are other symptoms of the disease.

• golgi

• Cystic Fibrosis: Thick mucus in the lungs; frequent lung infections; clogged pancreas; digestive problems; salty sweat. SALT HAS PROBLEMS ENTERING AND LEAVING THE CELLS of the lungs and pancreas.
