nounˌɛndəʊˈplazmɪkˌendōˌplazmik rəˈtikyələm
mass nounBiology A network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.
 Example sentencesExamples
-  However, the contributions of other membrane compartments, such as the plasma membrane, vacuoles, and endoplasmic reticulum, have not been investigated.
 -  It is also present in smaller amounts in the membranes of the mitochondria and endoplasmic reticulum within the cells.
 -  Elongation and unsaturation of fatty acids occurs in both the mitochondria and endoplasmic reticulum (microsomal membranes).
 -  Slower-mobility products result from improper processing in the endoplasmic reticulum, which is likely the result of misfolding.
 -  Many tumor cells contained scattered cytoplasmic particles consistent with glycogen, mitochondria, and rough endoplasmic reticulum.
