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.
Ribosomes on the rough endoplasmic reticulum are called âmembrane boundâ and are responsible for the assembly of many proteins. This process is called translation. Certain cells of the pancreas and digestive tract produce a high volume of protein as enzymes.t is âsmoothâ because it is not studded with ribosomes and is associated with smooth slippery fats. CELLS NEED THE ROUGH AND THE SMOOTH. Think of a cell as a âmultitude of membranesâ we said in an earlier section. This statement certainly applies to the endoplasmic reticulum an organelle found in eukaryotic cells.
