Liquid mosaic model easily explained
The liquid mosaic model was developed in the 1970s to describe how biomembranes are built and organized. Although the model is now out of date, giving a lecture or presentation about it can be very interesting and insightful.
Basic assumptions of the liquid mosaic model
In order to explain the liquid mosaic model in an easy and understandable way, you should break it down to the basic assumptions and explain them step by step. You can do this as follows:
- First, explain to your classmates that the liquid mosaic model is about the nature of biological membranes, and explain this term if necessary.
- Then point out that, according to the liquid mosaic model, these membranes consist of a double lipid layer that is not rigid, but rather has a "liquid" consistency.
- To make this point clear, you could, for example, draw a cell on the blackboard and show the membrane schematically as a liquid ring around it.
This is how you explain the nature of biomembranes
After you have explained the consistency of a biomembrane as described above, the rest of the Liquid mosaic model, which relates to the construction and organization of these membranes, easily explain.
Water is liquid in the temperature range between 0 ° C and 100 ° C. It's hard to ...
- To do this, simply draw a few proteins in the cell membrane and point out that, according to the model, they are in random or are distributed in a mosaic-like manner.
- Then note and explain that the various proteins are freely in the membrane according to the liquid mosaic model can move and in this way operate diffusion and the transport of various substances through the membrane enable.
- Finally, you should also mention that the liquid mosaic model is considered obsolete because it does not take into account, among other things, that the proteins contained in the membrane influence each other and that the membrane itself is by no means completely disorganized is.
The danger in explaining biochemical models is to compromise the audience by using too many Technical terms to slain. If you present the liquid mosaic model in this way, your classmates will certainly understand it quickly and will also be able to remember it well.
