Information and metabolism in bacterial chemotaxis (Q742654)

Summary: One of the most important issues in theoretical biology is to understand how control mechanisms are deployed by organisms to maintain their homeostasis and ensure their survival. A crucial issue is how organisms deal with environmental information in a way that ensures appropriate exchanges with the environment -- even in the most basic of life forms (namely, bacteria). In this paper, I present an information theoretic formulation of how \textit{Escherichia coli} responds to environmental information during chemotaxis and, more generally, a cybernetic model of the relationship between information and biophysical (metabolic) dynamics.
