What is the function of a smooth endoplasmic reticulum?
smooth endoplasmic reticulum performs a number of important metabolic functions in the cell. The exact function changes depending on the specific type of cell. When a non -abolishing compound, a smooth endoplasmic reticulum acts as a storage site until the metabolism begins again. Other important functions are detoxification of compounds brought to the cell and wrapping of newly formed proteins.
The general appearance of a smooth endoplasmic reticulum is a membrane composed of each other, a feature that significantly increases the surface area where metabolic processes can occur without excess space in the cell. Origallele gets its name from its appearance under a microscope; A similar organelle, a harsh endoplasmic retikula, has a collection of granules that produce proteins. One of the primary functions of smooth endoplasmic reticulum is the production of lipids, the basic components of the outer membrane of the cell. Another feature that he performs in all cells, yekonečný glucose production, energy storage molecule.
Smooth endoplasmic reticulum also metabolizes natural and ingested toxins in all types of cells. Metabolization of naturally produced toxins is a continuous process; The cell would die quickly if this function was not performed. Smooth endoplasmic reticulum of liver cells metabolizes commonly ingested toxin: alcohol.
Other functions of smooth endoplasmic reticulum depend on the type of cell. For example, in a muscle cell is responsible for the release of calcium ions when it receives a signal that the muscle cell must be downloaded. This function of smooth endoplasmic reticulum is so specialized in muscle cells that the organelle has a different name: scarcoplasmic reticulum.
Another specialized function of smooth endoplasmic reticulum is its role in the gonads of animal species. Instead of release of calcium ions, in these cells it helps in the last stages of steroid production. By a unique featureThis process is that smooth endoplasmic reticulum and mitochondria, other organelles, cooperate in the production of steroids. This is exceptional because most organelles work as independent units in maintaining the life functions of the cell.
Some genetic disorders disrupt smooth endoplasmic reticulum. In cystic fibrosis, the body cannot properly create a certain protein. This mutated protein was stuck in a smooth endoplasmic reticulum during the package and is unable to leave the cell. As a result, the lungs of a person with this condition are scarred and its lifetime has been seriously shortened.
