1.	In lac operon...act as inducer.
Answer» ac OPERON lactose acts as inducer. Extra Information :- Lactose is the substrate for the enzyme beta-galactosidase. Lactose regulates the switching on and off of the operon. In absence of a PREFERRED carbon source such as glucose, if lactose is provided in the medium of growth of the bacteria, the lactose GETS transported into the cells through the action of permease. A very LOW level of expression of lac operon is needed to be present in the cell at all times to allow the entry of lactose into the cells.
