A
PRRs.
B
PAMPs.
C
AMPs.
D
PMNs.
0 Comments
Verified step by step guidance1
Understand the key terms involved: PAMPs (Pathogen-Associated Molecular Patterns) are molecules found on bacteria that are recognized by the immune system, specifically by phagocytes.
Recognize that phagocytes have specific receptors that detect these PAMPs to initiate the immune response.
Identify that these receptors on phagocytes are called Pattern Recognition Receptors (PRRs), which bind to PAMPs to trigger phagocytosis and destruction of bacteria.
Differentiate PRRs from other options: AMPs (Antimicrobial Peptides) are molecules that kill microbes directly, PMNs (Polymorphonuclear leukocytes) are a type of phagocyte, and PAMPs are the bacterial molecules themselves, not receptors.
Conclude that the correct term for the receptors on phagocytes that bind PAMPs is PRRs.
