Answer:

B. They are broken down.

Explanation:

     The rough endoplasmic reticulum, thanks to the presence of ribosomes, is responsible for much of the cell's protein production. The proteins manufactured in the RER ribosomes penetrate the pouches and move towards the Golgi apparatus, passing through the narrow and tortuous channels of the smooth endoplasmic reticulum.

Describe how the lac operon functions, and explain how it permits E. coli to produce the enzymes needed to break down lactose wh
Aleonysh [2.5K]
When the lac operon controls the expression of proteins in the E.coli cell that can break down lactose into two sugars, glucose and galactose. When lactose is present, it binds to the repressor that typically sits on the lac operon, changing the repressor's conformation such that it can no longer bind to the lac  operon. Because of this, RNA polymerase can now transcribe the gene into mRNA, <span>which in turn is translated into the proteins that can break down lactose.</span>
