Question

Jessica travels to a remote village in the Amazon jungle in order to work as a medical volunteer. While in this village, Jessica discovers a new animal species that has a very selective diet. She observes that this specific species eats only fruit and plant products. Intrigued by this new animal species and its unique diet, Jessica decides to study the alimentary canal of this organism. One finding that is particularly interesting to Jessica, however, is the mucosal layer of the stomach. She notes that one cell is missing.
Which of the following cells would most likely be missing from the new species’ stomach mucosa?

a) Chief cell, because it releases pepsin, an enzyme necessary for the digestion of proteins.
b) Goblet cell, because this organism does not need to release mucus along the alimentary canal.
c) Enteroendocrine cell, because this organism does not need to absorb as many food products.
d) Paneth cell, because this organism will not need to secrete substances that destroy bacteria.

Answer 1

The answer is probably A.

A fruit and plant diet is high in carbohydrates but has little in the way of protein.

The other 3 options are more general and probably too necessary for survival to lose.

Answer 2

Answer: Option A

Explanation:

The chief cells in the alimentary canal of the organism releases an enzyme which is helpful in the digestion of the protein.

The name of the enzyme id pepsin which is not required much in the body of the organism who feeds on the plants and plant extracts.

This is because the plants have higher amount of carbohydrates in it and less source of protein.

Hence, for the digestion of cellulose, pepsin is not required.
