This region also contains these membranes, but they do not contain ribosomes. And so that means this smooth Er isn't directly involved in synthesized proteins. Instead, the smooth Er functions to produce lipids or fats, as well as to detoxify toxins and drugs. Now, the next section we're going to examine is region number six. This is known as the Golgi apparatus, the Golgi complex, or simply the Golgi. It's named after scientists who came up who first noticed this type of structure within our cell.
