Smooth endoplasmic reticulum function

Smooth Endoplasmic Reticulum 61 With the SER, RER, lysosomes, other intermediate organelle compartments, and even the nuclear and mitochondrial envelope membranes, the Golgi is an integral part of the complex intracellular organelle network involving vesicular trafficking that enables uptake, sorting, degradation, biosynthesis, trafficking, and/or secretion of cellular proteins and lipids.

Kramer, in Human Physiology, Biochemistry and Basic Medicine, 2016 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. The smooth endoplasmic reticulum also carries out the metabolism of carbohydrates and steroids. In muscle cells, the smooth endoplasmic reticulum regulates calcium ion storage. The smooth endoplasmic reticulum like the rough endoplasmic reticulum is connected to the nuclear envelope. The smooth endoplasmic reticulum comprises tube-like structure located near the cell periphery. These tubules or tubes sometimes branch forming a network that is re...
