What are the differences between positive and negative feedback |
|
Definition
Negative is the most predominate in nature. Two examples of it are: when the body is cold-it shivers, when the body is hot-it sweats. Negative has afferent and efferent pathways.
Positive feed back is best given by the example: a break or tear occurs in a blood vessel, platlets adhere to the surface and release a chemical, the chemical attracts more platlets, the chemical feedback ends when a plug is formed. Another example of positive feedback is contractions during child birth, the chemical oxytoxan stimulates more frequent contractions |

What is the fluidic model |
|
Definition
Since a phospholipid bilayer is composed of a polar (hydrophillic) and non polar (hydrophobic) head, it has a very fluidic nature to it-constantly moving in order to maintain its properties in the presence of water. Furthermore, their are integral proteins that are lodged/anchored into the fluidic phospholipid bilayer to aid in stability and structure. These proteins will often have glycoproteins-receptor proteins too. |
