Which of the following statements about autoinducers in the context of acids and bases is incorrect?
A
Autoinducers are chemical signals used in quorum sensing.
B
Autoinducers can influence the pH of a solution.
C
Autoinducers directly neutralize acids and bases in a solution.
D
Autoinducers are typically involved in the regulation of bacterial gene expression.
Verified step by step guidance1
Step 1: Begin by understanding the concept of autoinducers. Autoinducers are chemical signals used in quorum sensing, which is a process that bacteria use to coordinate certain behaviors based on the density of their population.
Step 2: Consider the role of autoinducers in bacterial gene expression. They are typically involved in the regulation of bacterial gene expression, allowing bacteria to adapt to changes in their environment by altering gene activity.
Step 3: Evaluate the statement regarding autoinducers influencing the pH of a solution. While autoinducers can affect bacterial activity, which might indirectly influence the pH, they do not directly alter the pH themselves.
Step 4: Analyze the statement about autoinducers neutralizing acids and bases. Autoinducers do not directly neutralize acids and bases in a solution. Their primary function is signaling, not chemical neutralization.
Step 5: Conclude by identifying the incorrect statement. Based on the analysis, the statement 'Autoinducers directly neutralize acids and bases in a solution' is incorrect because it misrepresents the function of autoinducers.
