Catabolite repression
Explanation:
Catabolite repression is characteristic for prokaryotic organisms such as bacteria and this is the way to control metabolism.
It is called repression, because enzymes that are involved in other sugar's metabolism are inhibited (repressed). The system of catabolite repression have components such as:
