Taxis

Question 1

what is involved with taxis

Answer 1

-sanse and respond to gradients (pos or neg)
-ability to move away (swimming)
-complex regulitory coordination and network (sensing stimuli, controlling movement)
-chemotaxis (surface proteins-chemoreceptors, relays sensory input to flagellum or flagella, affects rotation of the flagellar motor

Question 2

what are the different stimuli and taxis

Answer 2

-osmotaxis (ionic strength)
-hydrotaxis (hydrated environment/ water
-phototaxis (graident of light intensity, scotophobotaxis- move away form presents of light, photoreceptor-protein)
-aerotaxis (oxygen)
-magnotaxis (magnetic field, guide for o2)

Question 3

you want to know if your bacterium is capable of sensing and moving in responce to a hydro carbon graident. in a chemotaxis assay, your bacteria exhibits motility but moves in ever direction what is the best explination

Answer 3

the hydrocarbon does not include chemotaxis responce
