What is endoplasmic reticulum?
Endoplasmic reticulum (ER), a continuous membrane structure in biology, is vital for the synthesis, folding, modification, and transport of proteins. It forms a series of flattened sacs within the cytoplasm of eukaryotic cells. An endoplasmic reticulum can be found in all eukaryotic cells (ER). The ER typically makes up more than 50% of the cell's membranous composition in animal cells. The two forms of ER, known as rough ER and smooth ER, can be distinguished by differences in certain morphological and functional properties.
