Answer :
Phagocytes are specialized cells of the immune system that are responsible for recognizing, engulfing, and destroying pathogens. Two of the most important molecules used for this are called pathogen-associated molecular patterns (PAMPs) and pattern recognition receptors (PRRs).
PAMPs are molecules that are found on the surface of many pathogens, but are not found on the surface of the host. Examples of PAMPs include lipopolysaccharide (LPS) and flagellin, both of which are found on the surface of bacteria. PRRs, on the other hand, are molecules found on the surface of the phagocyte that can recognize PAMPs. Examples of PRRs include Toll-like receptors (TLRs) and NOD-like receptors (NLRs).
When phagocytes encounter pathogens, they use various molecules on their surface to recognize and bind to the pathogen. When a phagocyte encounters a pathogen, the PRRs on its surface will bind to the PAMPs on the surface of the pathogen. This is the first step in the process of phagocytosis, which is the process by which phagocytes engulf and destroy pathogens.

Phagocytes recognize pathogens using pattern recognition receptors (PRRs) that attach to pathogen-associated molecular patterns (PAMPs) on the pathogen surface. Thus, the answer is PRR attaches to PAMP.
When phagocytes recognize pathogens, the pattern recognition receptor (PRR) on the surface of the phagocyte attaches to the pathogen-associated molecular pattern (PAMP) on the surface of the pathogen. PRRs are designed to detect PAMPs, which are molecular structures commonly found on pathogens. This interaction is crucial as it triggers the phagocyte to initiate a response to destroy the pathogen.
In conclusion, the correct answer is: PRR attaches to PAMP.
