flattened compartments called sacs.

makes streroids, eg, cholesterol, and
reproductive hormones

makes lipids
Smooth ER
lacks
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
