Question

multiple choice question

what are the compounds that are released by members of a biofilm that accumulate as the population grows and stimulate gene expression in its members?

inducer molecules
interferons
biofilmants
cytokines

Explanation:

Identify the function of the described compounds

The question asks for the compounds released by members of a biofilm that accumulate as the population grows and stimulate gene expression in its members. This process is known as quorum sensing, and the signaling molecules released to coordinate this behavior are called autoinducers or inducer molecules.

Evaluate the given options

• Inducer molecules: This term refers to the signaling molecules (autoinducers) that trigger gene expression changes during quorum sensing in biofilms.
• Interferons: These are eukaryotic signaling proteins (cytokines) involved in antiviral defense, not bacterial biofilm signaling.
• Biofilmants: This is not a standard biological term.
• Cytokines: These are broad categories of signaling proteins used by the host immune system, not bacterial signaling molecules in biofilms.

Answer:

• (A) Inducer molecules (Correct answer)
• (B) Interferons
• (C) Biofilmants
• (D) Cytokines
