Begin to cross the membrane while still being synthesized-C
Explanation:
The Endoplasmic Reticulum is a part of the endomembrane system of the cell which is mostly reponsible for the synthesis and modification of proteins, although synthesis of lipids in plant and animal are carried out here
For more synthesis of proteins, it
needs to be further transported into the Rough endoplasmic reticulum- the designated site for secretion after synthesis of proteins.
Also it has been found out that when this proteins enter the Endoplasmic Reticulum, they start to cross the membrane while still being synthesized.
