What components of the cell membrane contribute to the mosaic quality of the cell membrane?
The Phospholipids and other steroids like cholesterol
What strengthens the fluid mosaic and makes the plasma membrane more stable in animals?
Cholesterol?
What is the Relationship between mosaic and plasma membrane?
The plasma membrance is a mosaic model- thus named because the constituent molecules of the membrane, e.g. phospholipids, cholesterol, proteins, exist in a state of tight associations and fluidity. These associations resemble a mosaic.
What three things describes appearance of the cell membrane?
This membrane is called the fluid mosaic modelas it is a mixture of phospholipids, cholesterol, proteins and carbohydrates.
What molecules can freely cross the plasma membrane?
Proteins, Carbohydrates, and Cholesterol. (Check out, 'fluid mosaic')
What Components of the cell membrane constantly shift the?
The entire cell membrane shifts. It has cholesterol molecules embedded in it to slow it down somewhat. This is called the fluid mosaic model.
What material best describes a membrance?
The cell membrane is called the fluid mosaic model as it is a mixture of phospholipids, cholesterol, proteins and carbohydrates.
Does the fluid mosaic model describe the plasma membrane as a structure that is liquid and very rigid?
true
What term describes the structure of a cell plasma membrane because of its oily nature and embedded proteins?
The term used to describe the plasma membrane because of it's oily nature and embedded proteins is the fluid-mosaic model.The plasma membrane that surrounds each cell has two layers of phospholipids (fat with phosphorous attached).Each phospholipid molecule has a head that is attracted to water (hydrophilic) and a tail that repels water (hydrophobic) . Both the layers of the plasma membrane have the hydrophilic ends pointing to the outside forming the outer layer of the plasma membrane and the hydrophobic tails pointing inside and forming the inner layer of the plasma membrane.Proteins and substances such as cholesterol become embedded in the bi-layer of the plasma membrane giving it a mosaic look.At body temperature the plasma membrane has a liquid consistency like the vegetable oil and proteins and other substances are able to move across the plasma membrane. Due to this reason the plasma membrane is described using the term fluid-mosaic model.
Term used to describe a cell membrane means that the membrane contains different kind of molecules?
That kind of membrane in cells is called a mosaic membrane since the molecules are not all the same.
Why is the fluid mosaic model important?
The fluid mosaic model serves to describe the cell membrane and how it functions. The 'fluid' describes its nature, rather than being solid, and the 'mosaic' describes its many and different parts, such as proteins, phospholipids, and in some cases cholesterol.
Why is the membrane referred to as a fluid mosiac?
It is called that because the membrane is rather loose and moves easily since is a lipid. It is stabilized somewhat by cholesterol molecules (in animals cells only). The mosaic just means that there is more than one thing that makes up the membrane. Besides the cholesterol molecules there are various proteins embedded in the membrane as well.
