According to the fluid mosaic model, a membrane ________. A) is composed of a fluid bilayer of phospholipids between two layers of hydrophilic proteins B) is composed of a single layer of fluid phospholipids between two layers of hydrophilic proteins C) is composed of a mosaic of fluid polysaccharides and amphipathic proteins D) is composed of a fluid bilayer of phospholipids with embedded amphipathic proteins

Respuesta :

Answer:

Option D, is composed of a fluid bilayer of phospholipids with embedded amphipathic proteins

Explanation:

The fluid mosaic model is the depiction of plasma membrane whose main components are phospholipids, cholesterol, proteins, and carbohydrates.  

The structure of plasma membrane consists of two layers of phospholipid molecules which are amphipathic or amphipathic (they possess both polar hydrophilic and non-polar hydrophobic ends).  

Protein molecules also possess both polar and non-polar side chains. However, their poly hydrophilic linkages are towards the outer side and non-polar or hydrophobic linkage is towards the inner side.  

Option D is correct

According to the fluid mosaic model, a membrane is composed of a fluid bilayer of phospholipids with embedded amphipathic proteins.

The correct option is D.

What is the fluid mosaic model?

The fluid mosaic model depicts the cell membrane as a constantly flowing tapestry of various chemicals that are phospholipids, cholesterol, and proteins.

This movement assists the cell membrane in maintaining its function as a barrier between the inner and outside surroundings of the cell.

This model is proposed by SJ Singer and G. L. Nicholson in 1972.

Thus, the correct option is D.
