Answer to Question #126669 in Human Anatomy and Physiology for Ishaq Huda

Question

Analysis of a granular secretion indicates that is contains some DNA and RNA and membrane components such as phospholipid. What kind of secretion is this and why

Answer 1

The presence of membrane components such as phospholipid, DNA, and RNA implies that the cell was damaged during the process of secretion. This is consistent with a type of secretion known as holocrine. Holocrine secretions are produced in the cytoplasm of the cell and released by the rupture of the plasma membrane, which destroys the cell and results in the secretion of the product into the lumen.
