Cell Locomotion Flashcards
(12 cards)
Motility that allow cells to reach diff parts
Cell locomotion
Flagella do not rotate at a constant speed
-rotational speed decreased/increased depends PMF
-polarly and lopho are different from petri
Swimming Motility
Moves straight front and stops/reverse tail to turn
Polarly flagellated
-It tumbles to change direction
-flagella are all over
Petrichous flagellated
Straight, fast, it reverse it’s all flagella to rotate
Lophotrichously flagellated
Type IV pili
Requires energy
Moves into groups
Twitching Motility
Pseudomonas sp. and in myxobacteria
Twitching Motility
-Continuous, smooth, without aid of external propulsive structure
-Murag sausage lol
-Filamentous and rod-shaped in morphology
Gliding motility
It is helical intracellular protein track that interacts with gliding motor and extracellular adhesion proteins
Gliding motility
Flavobacterium and Myxococcus
