What is the function of the endoplasmic reticulum in a plant cell?
What is the function of the endoplasmic reticulum in a plant cell?
The endoplasmic reticulum (ER) is the port of entry of proteins into the endomembrane system, and it is also involved in lipid biosynthesis and storage.
What is the main function of RER?
Introduction on Rough and Smooth Endoplasmic Reticulum
| RER-Rough Endoplasmic Reticulum | SER-Smooth Endoplasmic Reticulum |
|---|---|
| They are found near the nucleus of the cell. | They are found away from the nucleus in the cell. |
| Their function is to synthesize proteins. | Their function is to synthesize lipids. |
Why is the rough ER important?
The function of the rough ER is to provide a place so ribosomes can produce proteins, and proteins are one of the most important things in a cell. Rough ER is the organelle that reads the DNA instructions to make the proteins. Also, the rough ER is involved in the transportation of proteins to the Golgi apparatus.
Which are functions of the endoplasmic reticulum ER?
The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.
What does rough ER in a plant cell do?
The rough endoplasmic reticulum (rough ER) is a part of the endomembrane system of the cell and a subset of the endoplasmic reticulum (ER). This organelle is primarily concerned with the synthesis, folding and modification of proteins , especially those that need to be delivered to different organelles within the cell, or secreted from the cell.
What does rough ER mean?
Rough Endoplasmic Reticulum Definition. The rough endoplasmic reticulum (rough ER) is a part of the endomembrane system of the cell and a subset of the endoplasmic reticulum (ER).
What are diseases caused by endoplasmic reticulum?
Endoplasmic reticulum (ER) dysfunction might have an important part to play in a range of neurological disorders, including cerebral ischaemia, sleep apnoea, Alzheimer’s disease , multiple sclerosis, amyotrophic lateral sclerosis, the prion diseases , and familial encephalopathy with neuroserpin inclusion bodies.
What does endoplasmic reticulum mean?
endoplasmic reticulum. noun. The endoplasmic reticulum is defined as a series of folded membranes in the cells which are associated with protein synthesis, storage and the movement of cellular materials. An example of the endoplasmic reticulum is the place that steroids are stored in the cells for later use.
