Q
Summary - What are the functions of ER
A
There are two types of ER.
Rough ER has ribosomes on its surface which produce proteins that are packaged and stored ready for transport as needed
Smoth ER has NO ribosomes on its surface so does not produce proteins, however they do produce Lipids, Steroids and hormones which again are packaged and stored ready for transport as needed
Smooth ER also plays a part in detoxifying organic chemicals. (Lots in the liver)
