Functions. The endoplasmic reticulum serves many general functions, including the folding of protein molecules in sacs called cisternae and the transport of synthesized proteins in vesicles to the Golgi apparatus. Rough endoplasmic reticulum is also involved in protein synthesis.
Dec 3, 2019 · The endoplasmic reticulum (ER) is an important organelle in eukaryotic cells. It plays a major role in the production, processing, and transport of proteins and lipids. The ER produces transmembrane proteins and lipids for its membrane and many other cell components including lysosomes, secretory vesicles, the Golgi appatatus, the cell membrane ...
Nov 1, 2023 · The endoplasmic reticulum is the cell organelle that originates from the cell’s nuclear envelope, synthesizes protein, and transports the proteins for cellular metabolism. Depending on the cell, the endoplasmic reticulum can occupy 50% of the cell volume.
Oct 31, 2023 · The endoplasmic reticulum (ER) is a series of interconnected membranous sacs and tubules that collectively modifies proteins and synthesizes lipids. However, these two functions are performed in separate areas of the ER: the rough ER and the smooth ER. The hollow portion of the ER tubules is called the lumen or cisternal space.
Contents. Home Science Biology Cells, Organs & Tissues. The endoplasmic reticulum. endoplasmic reticulum in protein biosynthesis. The endoplasmic reticulum (ER) plays a major role in the biosynthesis of proteins. Proteins that are synthesized by ribosomes on the ER are transported into the Golgi apparatus for processing.
The SER’s functions include synthesis of carbohydrates, lipids, and steroid hormones; detoxification of medications and poisons; alcohol metabolism; and storage of calcium ions. In muscle cells, a specialized SER called the sarcoplasmic reticulum is responsible for storage of the calcium ions that are needed to trigger the coordinated ...
