What is chemotaxis, and how does a peritrichous organism move towards a chmical attractant?
So let’s saythere is a chemical attractant available in your environment. How does that affectrandom walk? It still has to be random. It leans its way to that direction byway of BIASED RANDOM WALK. This is where I’m moving towards the attractant andrun longer if I’m moving away from the attractant I’ll switch to a tumblefaster so that over time I’ll move in the general direction that I’m trying tomove to. Chemo-taxis leads to a biased random walk.
