Another example is the complex "pepin" system of Thiomargarita species, especially T. magnifica. [11] The organelles of the endomembrane system are related through direct contact or by the transfer of membrane segments as vesicles. Despite these relationships, the various membranes are not identical in structure and function.

The Golgi apparatus (/ ˈ ɡ ɒ l dʒ i /), also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. [1] Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.
The endoplasm, along with its granules, contains water, nucleic acids, amino acids, carbohydrates, inorganic ions, lipids, enzymes, and other molecular compounds. It is the site of most cellular processes as it houses the organelles that make up the endomembrane system, as well as those that stand alone.
The ER, which is part of the endomembrane system, which makes up a very large portion of the cell's total membrane content. The ER is an enclosed network of tubules and sacs, and its main functions include protein synthesis, and lipid metabolism. There are 2 types of ER, smooth and rough.
Eukaryotic cell with endomembrane system Eukaryotic cells are some 10,000 times larger than prokaryotic cells by volume, and contain membrane-bound organelles . Eukaryote cells include a variety of membrane-bound structures, together forming the endomembrane system. [ 23 ]
The functions of the endoplasmic reticulum can be summarized as the synthesis and export of proteins and membrane lipids, but varies between ER and cell type and cell function. The quantity of both rough and smooth endoplasmic reticulum in a cell can slowly interchange from one type to the other, depending on the changing metabolic activities ...
The membrane of nuclear envelope and endomembrane vesicles are composed of similar membrane proteins. [49] These vesicles also share similar membrane proteins with the organelle they originated from or are traveling towards. [50] This suggests that what formed the nuclear membrane also formed the endomembrane system.
