What are the functions of smooth endoplasmic reticulum?

Answer 1

The smooth endoplasmic reticulum has functions in several metabolic processes, including synthesis of lipids, metabolism of carbohydrates and calcium concentration, drug detoxification, and attachment of receptors on cell membrane proteins. It is connected to the nuclear envelope. Smooth endoplasmic reticulum is found in a variety of cell types (both animal and plant) and it serves different functions in each. The Smooth ER also contains the enzyme Glucose-6-phosphatase which converts glucose-6-phosphate to glucose, a step in gluconeogenesis. Smooth ER consists of tubules and vesicles that branch forming a network. In some cells there are dilated areas like the sacs of rough endoplasmic reticulum. The network of smooth endoplasmic reticulum allows increased surface area for the action or storage of key enzymes and the products of these enzymes. The smooth endoplasmic reticulum is known for its storage of calcium irons in muscle cells.
The job of the smooth ER is to produce functions.

Answer 2

Smooth ER?

Lipid synthesis.
Is the distal extension of the rough endoplasmic reticulum and produces lipids, steroid compounds and detoxifies materials.
synthesises lipids; metabolises carbohydrates.
1. It synthesizes lipids (ex. phospholipids and steroids). For example, the ER in the ovaries and testes synthesize steroid hormones.

2. Enzymes in the smooth ER help regulate the amount of sugar released from liver cells into the blood stream.

3. Detoxifies alcohol and poison

4. storage of calcium ions

ex. Necessary for contraction of in muscle. When a nerve signal stimulates a muscle cell, calcium ions leak from the smooth ER into the cytoplasmic fluid, where they trigger the contraction of the cell.

5. In junction with the Golgi complex, it manufactures lysosomes (an organelle made of hydrolitic enzymes enclosed in a membranous sac which digests food) and peroxisomes (organelle which detoxifies poisons and creates hydrogen peroxide)
it puts water and nutrients in the cell

-It makes proteins and lipids that will be exported by the cell

-It controls the Calcium level in the muscles

-It detoxifies poisons, alcohol, and drugs

Answer 3

The smooth endoplasmic reticulum plays a role in lipid metabolism, including the synthesis of lipids and steroids. It also helps in detoxifying harmful substances by metabolizing drugs and alcohol. Additionally, the smooth ER stores calcium ions involved in muscle contraction and other cellular processes.
