What does endoplasmic reticulum do?
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 is smooth endoplasmic reticulum kid definition?
smooth endoplasmic reticulum (SER), meshwork of fine disklike tubular membrane vesicles, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that is involved in the synthesis and storage of lipids, including cholesterol and phospholipids, which are used in the production of new cellular …
What is the function of the smooth endoplasmic reticulum in a plant cell for kids?
Smooth endoplasmic reticulum (SER). Among its functions is the production of proteins and steroids, the maintenance of plasma membranes, and a pathway for molecules to move along.
What is the role of endoplasmic reticulum Class 11?
Endoplasmic reticulum performs the following functions: It is responsible for the production and secretion of steroid hormones. It is also responsible for the synthesis of essential lipids such as phospholipids and cholesterol. It is responsible for the metabolism of carbohydrates.
What does the smooth ER do animal cell for kids?
Smooth ER (SER) acts as a storage organelle. It is important in the creation and storage of lipids and steroids.
What is endoplasmic reticulum and it functions Class 9?
The large network of membranous sheets and tubes is called endoplasmic reticulum. They are filled with fluids and carries materials throughout the cell due to which it is also called transport system of the cell. It transports materials between the regions of cytoplasm or between the cytoplasm and nucleus.
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 is the function of the endoplasmic reticulum in an animal cell?
The endoplasmic reticulum (ER), is a network of tubes and vesicles, or transporting molecules, inside an animal cell next to the nucleus. The main functions of the endoplasmic reticulum include synthesizing protein molecules; synthesizing lipids and fats, like cholesterol; and the metabolism of drugs and medicines.
Is endoplasmic reticulum found in plant or animal cells?
The endoplasmic reticulum is an organelle found in eukaryotic cells (or animal/plant cells). It basically consists of two parts, the smooth ER and the rough ER. It’s job includes protein translation (translating DNA and RNA ), creation and transport of proteins, carbohydrates and other nutrients needed by the cell.
What is the function of sarcoplasmic reticulum?
The sarcoplasmic reticulum (SR) is an organelle found in specific types of muscle fibers. Its function is to store calcium ions and then release them into the body, where they are absorbed when the muscles are in a relaxed position and released as the muscles contract.
