And when some type of action potential or some type of stimulus stimulates the cell to release these granules, they can basically be released via the process of exocytosis. And these glycoproteins can also be stored in these organelles we call lysosomes. Remember, lysosomes are these organelles that have these special digestive enzymes which are responsible for actually breaking down different types of molecules that are found within our cell. So, once again, to summarize, at position one, we have ribosomes attach the cytoplasmic side of the Er. These dots basically synthesize the proteins. And as the proteins are being synthesized, and as they move into the lumen of our endoplasmaticulum, special protein enzyme complexes basically attach those sugar molecules via the end glycocytic linkages.
