Standard 1e Preknowledge
1e) Students know the role of the endoplasmic reticulum and Golgi apparatus in the secretion of proteins.
CALIFORNIA FRAMEWORKS SUMMARY:
There are two types—rough and smooth—of endoplasmic reticulum (ER), both of which are systems of folded sacs and interconnected channels. Rough ER synthesizes proteins, and smooth ER modifies or detoxifies lipids. Rough ER produces new proteins, including membrane proteins. The proteins to be exported from the cell are moved to the Golgi apparatus for modification, packaged in vesicles, and transported to the plasma membrane for secretion.
