| 释义 | > as lemmasendoplasmic reticulum c. Cell Biology. A network of structures within the cytoplasm of a cell; esp. (more fully endoplasmic reticulum) a system of membranes in the form of tubules, cisternae, and vesicles, with or without surface ribosomes, which is involved in protein synthesis and other metabolic processes.When ribosomes are present on its surface, endoplasmic reticulum is known as granular, rough, or rough-surfaced; when they are absent, it is called agranular, smooth, or smooth-surfaced.sarcoplasmic reticulum: see the first element.

Wilson Cell i. 17 The other [constituent of protoplasm], the spongioplasm or reticulum, is of a firmer consistency, and forms a sponge-like network. 1922 Proc. Pathol. Soc. Philadelphia 24 62 Erythrocytes revealing a more or less extensive reticulum (granulofilamentous substance) by the methods of vital staining may be conveniently designated ‘reticulocytes’. 1947 Jrnl.

(ed. 5) i. 31/1 The agranular reticulum must be distinguished from the other smooth, membranous elements in the cytoplasm such as the Golgi apparatus and vesicles. 2003 L. Moss What Genes can't Do iii. 82 For protein synthesis to resume the signal sequence must become associated with the surface of the endoplasmic reticulum, specifically with ‘docking proteins’ embedded in the ER membrane. < as lemmas |
