Which type of cell junction is primarily responsible for preventing the leakage of digestive enzymes from the stomach into the surrounding tissues?
Understand the Problem
The question is asking you to identify which type of cell junction is most important for preventing digestive enzymes from leaking out of the stomach. This requires knowledge of the different types of cell junctions and their specific functions in tissues.
Answer
Tight junctions
The cell junction primarily responsible for preventing the leakage of digestive enzymes from the stomach into surrounding tissues is the tight junction.
Answer for screen readers
The cell junction primarily responsible for preventing the leakage of digestive enzymes from the stomach into surrounding tissues is the tight junction.
More Information
Tight junctions form seal-like barriers between adjacent cells, which are crucial in tissues like the stomach lining to prevent leakage of harmful substances.
Tips
A common mistake is confusing tight junctions with other junctions like gap junctions or desmosomes, which have different functions.
