Secretory proteins

... to the ER. Ribosomes are what takes the mRNA and translates it into proteins/enzymes. If the protein is bound for the outside (extracellular) ... made protein/enzyme will bud off from the ER's membrane forming its own secretory membrane around it to keep it from being exposed to the cytoplasm. ...

Just wanted to add that proteins incorporate many sugars for signaling purposes: either glycoproteins or proteoglycans. For example: Secretory vesicles in the Golgi cisterna use mostly mannose, galactose, and NAG (N-Acetlyglucosamine) to ...
