chemotaxis
Peritrichous CCW rotation
Peritrichous CW rotation
How cells with a single flagellum change direction
How to test chemotactic ability of mutants
baseline behavior of cells
behavior of cells in presence of attractant
Why study chemotaxis?
How do cells sense changes in levels of attractants/repellents and transmit info to flagellum?
CheA
CheY
CheZ
How do we get more runs than tumbles when more of an attractant binds?
How does a bacteria know if it is swimming up a gradient of an attractant?
CheA as a function of the amount of attractant outside the cell
Additional steps of adaptation if INCREASE in attractant levels
Additional steps of adaptation if DECREASE in attractant levels
