Which of the Following Skin Defenses and Its Mechanism Is

Question

Which of the following skin defenses and its mechanism is mismatched?
A) Lysozyme; hydrolyzes peptidoglycan in bacterial cell walls
B) Sebum; lipid hydrolysis leads to toxic by-products that inhibit microbial growth
C) Keratinized surface; protein that provides waterprooﬁng
D) Antimicrobial peptides; disrupt positively charged bacterial membranes

Accepted Answer

Antimicrobial peptides typically disrupt bacterial membranes through a mechanism that targets the membrane's lipid components, not specifically the charge of the membranes. They can act against a broad spectrum of microbes, including bacteria, fungi, and even some viruses, by integrating into and disrupting their membranes, but the description provided simplifies their action and inaccurately focuses on the charge aspect.
