Final answer:
Pattern Recognition Receptors (PRRs) are responsible for recognizing conserved sequences on pathogens and initiating the innate immune response. The correct option is E.
Step-by-step explanation:
The type of receptor that recognizes conserved amino acid and carbohydrate sequences on the surface of pathogens is known as Pattern Recognition Receptor (PRR).
These receptors are crucial for the innate immune response, as they can identify pathogen-associated molecular patterns (PAMPs), which are molecules commonly found on pathogens.
PRRs, such as Toll-like receptors (TLRs), are found on phagocytes and other cells of the immune system and are responsible for recognizing characteristic features of a pathogen.
