How Do the Endoplasmic Reticulum and Golgi Apparatus Function?
The endoplasmic reticulum (ER) is divided into rough ER (with ribosomes) and smooth ER (without ribosomes). Rough ER synthesizes proteins, while smooth ER is involved in lipid synthesis and detoxification. The Golgi apparatus modifies, sorts, and packages proteins and lipids received from the ER, preparing them for transport to their destinations.
