The smooth endoplasmic reticulum is the organelle responsible for the production of lipids in the cell. This particular reticulum also synthesizes carbohydrates and steroid hormones.Continue Reading
The endoplasmic reticulum is made up of membranous sacs and tubules. It has two different portions: the smooth endoplasmic reticulum and the rough endoplasmic reticulum. The rough endoplasmic reticulum is studded with ribosomes and produces proteins that are incorporated into cellular membranes outside of the cell.
The smooth endoplasmic reticulum lacks ribosomes on its cytoplasmic surface. It is especially important in muscle cells, where the specialized sarcoplasmic reticulum stores calcium ions, which are needed for triggering contraction of muscle cells.Learn more about Cells
Synthesis of lipids takes place at the smooth endoplasmic reticulum. ER, or endoplasmic reticulum, refers to a network of sacs and membrane-enclosed tubules that starts from the nuclear's membrane all through the cytoplasm.Full Answer >
The smooth endoplasmic reticulum, or smooth ER, performs functions in several metabolic processes, including synthesis of steroids, lipids and phospholipids, as well as the metabolism of carbohydrates, elimination of drugs from the system and attachment of receptors to cell membrane proteins. Both the smooth and rough endoplasmic reticulum form an organelle in eukaryotic organisms creating a network of tubes or sacs called cisternae, but it is the smooth endoplasmic reticulum that helps the body eliminate a number of toxins.Full Answer >
The difference between a cell and an organelle is that an organelle is part of a eukaryotic cell. While a cell is typically considered to be the smallest self-contained part or independently functioning unit of an organism, organelles are smaller structures within eukaryotic cells that carry out various functions.Full Answer >
An organelle is a unique part of a cell that has a specific function. The term is a combination of the word "organum," which means instrument or engine, and the suffix "-elle," which means small.Full Answer >
