Solution
Sweat glands located on the body surfaces accomplish the following:
-
Inhibit bacterial growth by lowering pH: Sweat is slightly acidic, which can create an environment that is inhospitable to certain bacteria, thereby inhibiting their growth.
-
Destroy bacterial cell walls by secreting antimicrobial molecules: Sweat glands produce and secrete antimicrobial peptides, such as dermcidin, which can destroy the cell walls of bacteria.
The other options are not typically functions of sweat glands:
- Sweat glands do not destroy bacterial cells by secreting proteins that inhibit replication.
- Sweat glands do not destroy bacterial cells by producing leukocytes. Leukocytes, or white blood cells, are part of the immune system and are not produced by sweat glands.
- Sweat glands do not destroy bacterial cell walls by producing antibodies. Antibodies are produced by immune cells, not sweat glands.
