The Endoplasmic Reticulum
The endoplasmic reticulum (ER) is a system of membrane-enclosed sacs and tubules in the cell.
Endoplasmic reticulum
The endoplasmic reticulum or ER (endoplasmic means "within the cytoplasm", reticulum means "little net") is an organelle found in all eukaryotic cells.
Endoplasmic Reticulum - Wrapping it Up
Another organelle in the cell is the endoplasmic reticulum (ER). While the function of the nucleus is to act as the cell brain, the ER functions as a packaging system. It does not work alone.
Endoplasmic Reticulum (Smooth)
Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes.
Endoplasmic reticulum (ER) appears to be a focal point for alterations that result in neuronal dysfunction and death in Alzheimer's disease (AD).
endoplasmic reticulum -- (ER) network of membranes in eukaryotic cells which helps in control of protein synthesis and cellular organization.
endoplasmic reticulum (ER) A network of membranous tubules in the cytoplasm of a cell; involved in the production of phospholipids, proteins, and other functions. Rough ER is studded with ribosomes; smooth ER is not. PICTURE ...

endoplasmic reticulum
a series of interconnected, flattened cavities lined with a membrane about 4 nm thick, which is continuous with the nuclear membrane.
Endoplasmic reticulum (ER) An extensive system of cytoplasmic membranes that comprises about half the total cell membrane.
Endoplasmic Reticulum - The Cellular Highway
How do you travel from home to school? Do you take a road, or sidewalk? Roads and sidewalks give people a path to follow as we move about our cities. A cell also has a system of tiny roads.
endoplasmic reticulum - labyrinthine, membrane-bounded compartment in the cytoplasm of eucaryotic cells, where lipids are synthesized and membrane-bound proteins are made.
Endoplasmic reticulum, shown in Figure 13 and 14, is a mesh of interconnected membranes that serve a function involving protein synthesis and transport.
endoplasmic reticulum Cytoplasmic organelle composed of a system of interconnected membranous tubules and vesicles; ER; rough ER has ribosomes attached to the side of the membrane facing the cytoplasm and smooth ER does not.
Rough endoplasmic reticulum (RER)
A network of interconnected membranes forming channels within the cell.
Rough Endoplasmic Reticulum: Rough endoplasmic reticulum appears "pebbled" by electron microscopy due to the presence of numerous ribosomes on its surface.
Smooth endoplasmic reticulum (SER) is more tubular. It is the site of lipid synthesis and enzymes in the SER of the liver modify or detoxify hydrophobic chemicals such as pesticides and carcinogens.
That portion of the endoplasmic reticulum that is free of ribosomes.
smooth muscle
A type of muscle lacking the striations of skeletal and cardiac muscle because of the uniform distribution of myosin filaments in the cell.

Normally refers to the sequence (ca 20 amino acids) that interacts with signal recognition particle and directs the ribosome to the endoplasmic reticulum where co translational insertion takes place.
Produced in cells' endoplasmic reticulum, MHC proteins act as sentries in the war against intruders, recognizing them and identifying infected cells for destruction by specialized T cells.
GOLGI APPARATUS - A membranous, vesicular structure which is in continuity with the endoplasmic reticulum of eukaryotic cells and generally in close proximity to the nucleus, ...
These substances are organized to constitute the living organelles, as endoplasmic reticulum, ribosomes, chloroplasts, mitochondria, Golgi apparatus, nucleolus, nucleus, lysosomes, vacuoles, and centrosomes.
Proteins within the membrane of the vesicle recognize and attach to proteins in other membranes. This allows vesicles to attach to the membranes of other organelles such as the endoplasmic reticulum, golgi apparatus, or lysosomes.
A component of a cell with the proviso that the component is part of some larger object, which may be an anatomical structure, e.g. rough endoplasmic reticulum or nucleus, or a gene product group, e.g. ribosome, proteasome or a heterodimeric protein.
Ribosome (RYE-bo-sohm) A molecular complex in which proteins are made. In eukaryotic cells, ribosomes either are free in the cytoplasm or are attached to the rough endoplasmic reticulum.
After removal of the 24-amino-acid signal peptide from preproinsulin to form proinsulin, the latter polypeptide is further processed in the endoplasmic reticulum. This produces the final hormone, insulin, which is released from the cell.
