Question

What is one function of the smooth endoplasmic reticulum?

Answer 1

The smooth endoplasmic reticulum is primarily responsible for the synthesis of lipids, regulation of calcium ion concentrations, metabolism of carbohydrates, and detoxification of toxins.

Step-by-step explanation:

One function of the smooth endoplasmic reticulum (SER) is the synthesis of lipids, including phospholipids and steroid hormones. The SER is vital in cells that produce steroid hormones, such as the ovaries and testes, which is why these cells have a high concentration of smooth ER. Another critical role of the SER is to sequestrate and regulate the concentration of cellular calcium ions (Ca++), essential for neural functions like neurotransmitter release. Additionally, the SER plays a part in metabolizing carbohydrates and detoxification, working to break down various toxins.

Answer 2

The Smooth Endoplasmic Reticulum has a wide range of functions in carbohydrates and lipid synthesis. Phospholipids and cholesterol  are necessary for the construction of cell membranes. It serves as a transitional area for vesicles that transport ER products to various destinations. In liver cells, Smooth ER helps detoxify certain compounds. In muscle contraction, and in brain cells it synthesis male and female hormones.
