Multiple Choice

Which of the following is not true about adhesin molecules?

Adhesin molecules are receptors on the host cell's surface that allows pathogens to enter the cell.

Adhesin molecules are found on pili, fimbriae, and flagella of bacterial pathogens.

Adhesin molecules allow a bacterial pathogen to attach to the surface of the host's cells.

Adhesin molecules bind to receptors on the surface of the host cell.

Verified step by step guidance

Understand the role of adhesin molecules: Adhesin molecules are proteins or glycoproteins found on the surface of bacterial pathogens that facilitate attachment to host cells.

Identify the structures where adhesin molecules are located: They are commonly found on pili, fimbriae, and sometimes flagella, which are appendages that help bacteria adhere to host tissues.

Clarify the function of adhesin molecules: Their primary function is to bind to specific receptors on the host cell surface, allowing the bacteria to attach securely to the host cells.

Differentiate between adhesin molecules and host cell receptors: Adhesin molecules are not receptors on the host cell; rather, they are components of the pathogen that interact with host cell receptors.

Evaluate the statements: The statement that adhesin molecules are receptors on the host cell's surface is incorrect, as adhesins are part of the pathogen, not the host cell.
