Multiple Choice
Which of the following are considered bacterial pathogen-associated molecular patterns (PAMPs)?
A
Ribosomal RNA
B
Chlorophyll
C
Mitochondrial DNA
D
Lipopolysaccharides (LPS)
Verified step by step guidance
1
Understand the concept of pathogen-associated molecular patterns (PAMPs). PAMPs are molecules associated with groups of pathogens, recognized by cells of the innate immune system.
Identify the characteristics of bacterial PAMPs. These are typically conserved molecular structures found on the surface of bacteria that are recognized by the immune system.
Review common examples of bacterial PAMPs. Lipopolysaccharides (LPS) are a well-known example, found on the outer membrane of Gram-negative bacteria.
Analyze the options given: Ribosomal RNA, Chlorophyll, Mitochondrial DNA, and Lipopolysaccharides (LPS). Determine which of these are typically associated with bacteria and recognized by the immune system.
Conclude that Lipopolysaccharides (LPS) are the correct answer, as they are a classic example of bacterial PAMPs, recognized by the immune system to trigger an immune response.
