= = = = =**What is a Smooth Endoplasmic Reticulum?**= = = =What is the Smooth Endoplasmic Reticulum responsible for?= = = =**The structure of a Smooth Endoplasmic Reticulum**=
 * Smooth Endoplasmic Reticulum is a membrane organelle that transports newly synthesized proteins to other locations in the cell or outside the cell and also manufactures lipids.**
 * A SER (Smooth Endoplasmic Reticulum) is made up of lipids, which are fatty compounds. The SER is responsible for many things including the facilitation of protein folding and then transporting those synthesized proteins. These proteins are transported through the cell in a pouch called the cisternae. The cisternae is a flat disc that makes up the Golgi Apparatus. SER is also responsible for insertion of proteins into the endoplasmic reticulum membrane, drug metabolism, to disulphide bond formation and rearrangement, and is also a part of Glycolosis. Also, the SER is in charge of lipid synthesis, carbohydrate metabolism, and calcium concentration. Drug detoxification, and attachment of receptors on cell membrane proteins are also on that list.**
 * Most SER structures are a membranous network of cisternae that are held together by the cytoskeleton, which is just a cellular skeleton for the cell that it is protecting.**

=**Other**=
 * -SER looks like a deflated balloon and is considered a storage space for cells.**
 * -Many things are stored in the SER.**
 * -Unlike the Rough Endoplasmic Reticulum (RER), the SER has no ribosomes, which is why it is smooth.**
 * -The SER is a transport organelle and is evenly distributed among the cytoplasm.**
 * -SER forms a separate sealed interconnecting network.**
 * -SER is also involved in the production pf steroid hormones in the adrenal cortex and also in the endocrine glands.**
