What is an analogy of rough and smooth ER?

Answer 1

Smooth ER is like a factory, or processing plant, that makes fats and certain hormones (steroids), processes carbohydrates, and controls calcium, and helps in detoxification.

Endoplasmic reticulum (ER) is like a manufacturing plant, much like a factory, where proteins and lipids (fats) are made. This is also where things are packaged into boxed and sent off to different places. In the cell the smooth ER is a network of membrane bound bodies which lack ribosomes (the molecules used in protein synthesis) and its primary function is to modify, encapsulate and transport newly synthesized proteins and lipids which will be secreted or remain in the cytoplasm as membrane bound vesicles. The smooth ER can also be compared to a highway, or a protein and lipid highway, if you will. It is sometimes called the transitional ER because it contains exit sites from which transport vesicles carrying these proteins and lipids bud off for transport to the Golgi apparatus. It is usually prominent in cells that specialize in lipid (fat) metabolism and synthesis.

Answer 2

A ribosome is like a honeybee as they both produce materials needed according to the directions given to them.

Answer 3

Halls in a house wold be good, or stairways

Answer 4

I suppose you could say the smooth ER is analogous to the hallways of a school. That is assuming that students represent proteins.

Answer 5

Some say that the ER is like hallways in a factory. They carry instructions or products from one place to another.
