What is SER and RER?
The smooth endoplasmic reticulum (SER) is distinguished from the rough endoplasmic reticulum (RER), the other basic type of endoplasmic reticulum, by its lack of ribosomes, which are protein-synthesizing particles that can be found attached to the outer surface of the RER to give the membrane its “rough” appearance.
What is the role of smooth endoplasmic reticulum?
The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum.
Is smooth ER plant or animal cell?
The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.
What is SER and RER give one function of each?
(i) Rough endoplasmic reticulum (RER) has ribosomes on its surface and therefore helps in the synthesizing proteins. (ii) Smooth endoplasmic reticulum (SER) helps in the manufacture of fat molecules or lipids.
What is the function of the mitochondria?
Mitochondria. Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
What does the SER do?
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 are the three functions of SER?
What is the function of SER?
- Synthesises glycogen, lipids and steroids.
- It helps in the formation of spherosomes/ Oleosomes.
- Provides vesicles for cis-face of Golgi apparatus.
What is the function of SER in animal cell?
What is the function of the SER?
How was mitochondria formed?
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.
What is SER why it is important?
The SER helps in metabolism of number of different types of molecules particularly lipids. They also help to detoxify the harmful drugs. In some cells SER is responsible for transmission of impulses, e.g muscle cells, nerve cells.
