The ER extends from the outer surface of the nuclear membrane into the cell body. Rough ER is a host for ribosomes that continually attach to and detach from the ER surface. The rough ERâs main function is to help form and store proteins, while smooth ERs store lipids, a type of fat.

For a high school course to have the AP designation, the course must be audited by the College Board to ascertain that it satisfies the AP curriculum.
