Verified step by step guidance

Understand the role of Pattern Recognition Receptors (PRRs): PRRs are proteins used by the immune system to identify pathogen-associated molecular patterns (PAMPs) that are commonly found on pathogens but not on host cells.

Identify common PAMPs: These include structures like peptidoglycan, flagellin, lipopolysaccharide, and foreign nucleotide sequences, which are typically found on bacteria and viruses.

Consider the nature of glycolysis enzymes: Glycolysis enzymes are involved in the metabolic pathway of glycolysis, which is a process that occurs in both host and pathogen cells.

Evaluate the likelihood of detection: Since glycolysis enzymes are present in both host and pathogen cells, they are not unique to pathogens and thus are less likely to be detected by PRRs.

Conclude which option is least likely to be detected by PRRs: Based on the understanding that PRRs detect unique pathogen structures, glycolysis enzymes are the least likely to be detected as they are not pathogen-specific.
