The lac operon, which stands for Lactose operon is known as an inducible system. It is the an operon required for the transport and metabolism of lactose some enteric bacteria (Echerichia coli for example). The Lac operon is only activated in the presence of a key molecule. The key molecule is lactose.
From the given options the following best describes the Lac operon:
D. The repressor is freed from the operator when lactose is present.
Plants would be the only option, they have no legs so they can't move. They are producers and make its own food and unable to move around its environment.
Hm, raw materials: three stages exist in the electron transport: It is, glycolysis, citric acid cycle, and electron transport.
In animals, like humans, waste products of aerobic respiration is, water and carbon dioxide, and waste product of anaerobic respiration are lacic acid.
Hope this helps alot!! -Aparri
