Individual bacteria respond to environmental<br />
change by regulating their gene expression<br />
A bacterium can tune its metabolism to the changing<br />
environment <strong>and</strong> food sources<br />
This metabolic control occurs on two levels:<br />
Adjusting activity <strong>of</strong> metabolic enzymes<br />
Regulating genes that encode metabolic enzymes<br />
Bacteria <strong>of</strong>ten respond to environmental<br />
change by regulating transcription<br />
Natural selection has favored bacteria that produce only<br />
the products needed by that cell<br />
A cell can regulate the production <strong>of</strong> enzymes by feedback<br />
inhibition or by gene regulation<br />
Gene expression in bacteria is controlled by the operon<br />
model
