All of the Following are Protective Factors of the Skin

Question

All of the following are protective factors of the skin and its secretions EXCEPT
A)keratin.
B)tightly packed cells.
C)lysozyme production.
D)pyocyanin production.
E)salt.

Accepted Answer

Pyocyanin production is not a protective factor of the skin and its secretions. In fact, pyocyanin is a pigment produced by certain bacteria, including Pseudomonas aeruginosa, which can cause infections in the skin and other parts of the body. The other choices, keratin, tightly packed cells, lysozyme production, and salt, all contribute to the protective function of the skin and its secretions.
