a. Compare and contrast the Sec and Tat systems in bacteria. b. Why do Gram-negative bacteria need one- and two-step secretion systems? What is the difference between these two systems? c. There has been a recent outbreak of a bacterial infection in humans that causes high fever, vomiting, and diarrhea. You identify the cause of this infection as a pathogenic Gram-negative bacterium called Bacterium Q, or, more specifically, the Q toxin secreted by this bacterium. Make a hypothesis about the type of secretion system this pathogen has and explain how this secretion system works to secrete Q toxin.
