The name for bacteria with tufts of flagella emerging from the same site is ?
|
Lophotrichous
|
|

|
4 rings
|
|
|

2 rings
|
|
|
The Flagellum's main anchor is the ?
|
Cell membrane
|
|
|
What force makes a flagellum spin? which is also known as ?
|

Chemiosmosis |
|
|
What type of gradient makes up the Proton Motive Force/Chemiosmosis?

|
|
|
What part of H+ makes up the electrical part and which part of H+ makes up the chemical part?
|
the + part of H+ makes up the electrical
the H part of H+ makes up the chemical the H part is also known as the element difference |
|
|
H+ is ? because the H and + are in one spot
|
electro-chemical
|
|
|
H+ gives up its energy(the +) when it moves from the ? space back into the ?
|
periplasmic
cytoplasm |
|
|
? works the same way as ATP synthase
|
flagellin
|
|
|
H+ moving from the ? space down it's gradient, causes H+ to give up it's ? which creates energy to rotate the flagellum.
