Two component systems are common in bacteria to regulate the expression of specific genes in response to environmental signals. Which of the following can be said of two component systems? (mark all the answers that apply) An intracellular response regulator is involved in the response. A membrane-bound sensor kinase is typically involved. A membrane transporter is required to transport a molecular signal into the cell, which then serves as an inducer of transcription for an operon. Molecules are pumped out of the cell through one molecular compnent, and transported back in through a second molecular component.
