Explain the fluid mosaic model

1 answer:

3 0

The model describes how cellular membranes i.e. lipid bilayers are organized. Despite the fluidity, lipid bilayers can form certain domains with different characterisrics and compositions. The cell can use different mixtures of lipids to create a 'mosaic' or 'patchwork' of domains.
An example of such domains are so called 'lipid rafts' which are aggregates of certain lipids (mostly cholesterol and sphingomyelins). In these rafts the lateral diffusion of membrane-bound proteins is strongly reduced, thereby forming stable complexes to facilitate, for example, signal-processing and transduction.
Note that a lot about how or why a cell creates these domains is still unknown.

Motor end plates are associated with

Mazyrski [523]

Motor end plates are associated with muscular contractions. Motor end plates are the large and complex end formation of a motor neuron that builds contact with the skeletal muscle fibers. Without motor end plates, muscular contractions will not be possible. This works highly during emergency situations where the body takes a fight or flight reaction. 

A good example is when the fingers touch a burning candle; these motor end plates get quick impulses from the brain and send signals to the muscles to move it away to prevent further damage to the body. Without motor end plates we would be in a heap of trouble as this is the mechanism of the body responsible for motor skills and quick reaction time.

Water is said to have a high boiling point. How does this property of water allow for life in the oceans

kompoz [17]

What does this mean for us? Water's polarity allows it to dissolve other polar substances very easily. When a polar substance is put in water, the positive ends of its molecules are attracted to the negative ends of the water molecules, and vice versa.
