The Endomembrane System!!!

  The Endomembrane System is very important in our cells. Eukaryotic cells are the only cells that have the endomembrane system. It consists of the the nuclear envelope, the endoplasmic reticulum (smooth and rough), the golgi apparatus, lysosomes, different types of vesicles and vacuoles, and the plasma membrane. The function of the Endomembrane System deals mostly with proteins. It includes the making, modification, sorting, and transport of proteins. All of the Endomembrane System is related by either physically touching or by vesicles transferring between the related organelles.
  Within the Endomembrane System there are many different organelles that have certain responsibilities in the cell. The nuclear envelope is a bi-layer membrane that encompasses the nucleus of cells. The endoplasmic reticulum is the place that proteins are synthesized and transported. Proteins are modified and also transported to other parts of the cell in the golgi apparatus. Lysosomes have a digestive enzyme that allows them to digest macromolecules in the cell. Vesicles are small bits of membranes that are used to transport substances in the cell. Vacuoles are used to store waste products and maintaining the shape of cells. The gatekeeper or plasma membrane of the the cell is used to regulates what enters and exit the cells.
  Endomembrane System consists of most of the membranes in the cells and has many different resposibilities in our cells that are imperative to our bodies.
