Definition of the Smooth ER. The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function.The main function of the smooth ER is to make cellular products like hormones and lipids.he interior of the smooth ER is called the lumen, which is enclosed by a phospholipid membrane, just like the membrane that encloses the entire cell. The number of smooth ER units in a cell depends on the type of cell and what its manufacturing needs are.
In liver cells the smooth ER contains enzymes for the detoxification of harmful drugs and metabolic by-products. In the reproductive organs, smooth ER in the cells produces the steroid hormones testosterone and estrogen.xamples of protein synthesis by the rough endoplasmic reticulum are the proteins produced in secretory cells. These include the digestive enzymes produced in the stomach and the protein hormones like insulin produced in the pancreas.
