An immune system cell called the plasma cell produces thousands of antibodies (a type of protein) per second for release into the body. What type of intracellular structure would you expect to be very prominent within the cell?
A) the smooth endoplasmic reticulum
B) the rough endoplasmic reticulum
C) peroxisome
D) microtubules

The rough endoplasmic reticulum (RER) is responsible for protein synthesis and is where the antibodies would be produced in the plasma cell. As the antibodies are proteins, a large and active RER would be necessary in the cell. The other structures mentioned (smooth endoplasmic reticulum, peroxisome, microtubules) would not be directly involved in the production of antibodies.
