makes streroids, eg, cholesterol, and
reproductive hormones
makes lipids
Smooth ER

ribosomes
Endoplasmic small sacs break off to form the Golgi
Reticulum Rough ER Body
contains ribosomes
proteins made by ribosomes enter sacs and
move through them, also get modified on the

components.
adds sugar to the proteins- makes a glycoprotein
