"Chitin Synthase is manufactured in the rough endoplasmic reticulum of fungi as the inactive form, zymogen. The zymogen is then packaged into chitosomes in the golgi apparatus. Chitosomes bring the zymogen to the hyphal tip of a mold or yeast cell membrane. Chitin synthase is placed into the interior side of the cell membrane and then activated.
