The endomembrane system is composed of the different membranes that are suspended in the cytoplasm within a eukaryotic cell.These membranes divide the cell into functional and structural compartments, or organelles.he plasma membrane is a phospholipid bilayer membrane that separates the cell from its environment and regulates the transport of molecules and signals into and out of the cell. Embedded in the membrane are proteins that perform the functions of the plasma membrane.
The transmembrane proteins that cross the bilayer are very important in the active transport of ions and small molecules. Different Membranes of the Cell As you learn more about cell organelles, you will find that they all have a membrane. Organelle membranes do not have the same chemical makeup as the cell membrane. They have different lipids and proteins that make them unique. The membrane that surrounds a lysosome is different from the membrane around the endoplasmic reticulum. Some organelles have two membranes.
