Endoplasmic Reticulum: Important Cell Organelle
What is - definition
The Endoplasmic Reticulum is an organelle present within the cells of eukaryotes (presence of cell nucleus and various organelles).
- Formed from plasma membrane invagination;
- Formed by tubules and flattened vesicles;
- Has connection to the library (nuclear wrap);
- RE membranes surround spaces that are separated from the rest of the cell.
- Acts in the process of synthesis and transport of proteins;
- Participates in lipid metabolism;
- It also acts on intracellular transport (inside the cell).
Rough Endoplasmic Reticulum
- Ribosomes are adhered to the membrane, acting on protein production.
Smooth Endoplasmic Reticulum
- do not have membrane-bound ribosomes;
- Composed of a system of cylindrical tubules;
- They act in the production of hormones and lipids.
- The endoplasmic reticulum was first visualized in 1945 by Belgian biologist Albert Claude.
