Document Summary
Lecture 8: counterclockwise rotation moves cell toward attractant. The cells have receptors that can identify attractants or repellents. They also are responsible for the length of time the rotator turns in one direction. Relating to the picture these: ccw toward attractant. Can only go clock wise or counter clock wise, changing direction causes the bundle to fall apart. Chemotaxis: movement of an organism in response to a chemical stimulus. Phototaxis: the bodily movement of a motile organism in response to light, either toward the source of light she"s only interested in the major organelles and how the relate to something this is. One or many; polar or (cid:498)peritrichous(cid:499) in eukaryotic cells. The flagella motor anchors the bacteria and archaeal fkagella. Hellical flagellum consists of long assembly of flagellin proteins monomer h-antigen. Flagellar mothers embedded in cell wall/plasma membrane and rotation driven by the proton motive force. This cell moves similar to a boat motor.
