When both glucose and lactose are present in the media in which e. coli is growing, which is the preferred carbon source?

Sagot :

When both glucose and lactose are present in the media in which E. coli is growing the preferred carbon source of is glucose.

About lac operon:

  • The lac operon of E. coli contains genes involved in lactose metabolism which is expressed when lactose is present and glucose is absent.
  • The lac repressor and catabolite activator protein (CAP) are two regulators that control the operon's "on" and "off" states in response to lactose and glucose concentrations.
  • A lactose sensor is the lac repressor. When lactose is present, it ceases to function as a repressor, blocking transcription of the operon in its usual state. Through isomer allolactose, the lac repressor indirectly detects lactose.
  • The CAP serves as a glucose sensor. It starts the operon's transcription, but only when the blood glucose level is low. Through the chemical cAMP, CAP detects glucose in an indirect manner.
