First World War erupts Four days after Austria-Hungary declared war on Serbia, Germany and Russia declare war against each other, France orders a general mobilization, and the first German army units cross into Luxembourg in preparation for the German invasion of France.
The endoplasmic reticulum (ER) is a series of interconnected membranes or flattened sacs adjacent and connected to the nuclear membrane. The ER comes in two different morphological forms: smooth endoplasmic reticulum (sER) and rough endoplasmic reticulum (rER). The primary function of the sER is to serve as a platform for the synthesis of lipids (fats), carbohydrate (sugars) metabolism , and the detoxification of drugs and other toxins.
mRNA travels to the ribosomes on the Rough endoplasmic reticulum where tRNA bring amino acids to be joined together into polypeptide chains. These chains are 'coiled' up into protiens. Some of these proteins are enzymes. I would guess Rough ER. According to my A&P book, The cells of the secretory acini exhibit a high density of rough ER ---...but, there wasn't anything that outright said that it is the rough ER that is producing the enzymes. Sorry I can't be more positive about the answer..
