  3. 4 days ago · The endoplasmic reticulum (ER) is a part of a transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits – rough endoplasmic reticulum (RER), and smooth endoplasmic reticulum (SER).

  4. Jul 8, 2024 · The Endoplasmic Reticulum (ER) is an extensive, interconnected network of membranous structures located within the cytoplasm of all eukaryotic cells, playing a crucial role in the synthesis, folding, modification, and transport of proteins and lipids.

  5. Jul 17, 2024 · The endoplasmic reticulum (ER) is a system of membranous cisternae (flattened sacs) extending throughout the cytoplasm. Often it constitutes more than half of the total membrane in the cell.

  6. Jul 4, 2024 · The endoplasmic reticulum (ER) is a widely spread membrane system within the neuron that is continuous with the nuclear envelope. It consists of series of tubules, flattened sacs called cisternae, and membrane-bound spheres called vesicles.
