Which of These Regulates the Formation of Biofilms

Question

Which of these regulates the formation of biofilms?
A)photosynthesis
B)quorum sensing
C)water availability
D)catabolite repression
E)end product repression

Accepted Answer

Quorum sensing is a mechanism that helps bacteria sense and respond to changes in population density. This mechanism involves the production and detection of signaling molecules, which regulate gene expression and behavior in response to cell density. One of the behaviors regulated by quorum sensing is the formation of biofilms, which are communities of bacteria embedded in a matrix of extracellular polymeric substances. Therefore, choice B, quorum sensing, is the best answer for this question.
