<< On its surface, a bacterium has thousands of receptors that scan the environment and then tell it what to do >>
<< The receptors on the surface of a bacterial cell detect light, chemicals, edible things and poisonous things, and transmit that information to a deeper layer of proteins, called kinases, which interpret this data and translate it into a simple choice: “Keep going” or “Change direction!” >>
<< (..) one region of a kinase called CheA, changes its orientation in relation to the other proteins, in a motion called “dipping.” >>
