Answer:
answer is option (a) The less unsaturated the fatty acid, the more fluid nature.
Explanation:
S.J. Singer and GarthL. Nicolson proposed the fluid mosaic idea in 1972. The model explained the structure of the plasma membrane.
- Although the version has modified over time, it nevertheless satisfactory describes the shape and features of the plasma membrane as we currently understand them.
- The fluid mosaic version defines the plasma membrane's composition as a mosaic of components, which include phospholipids, cholesterol, proteins, and carbohydrates, that provide it a fluid appearance.
- The membrane's predominant material is made from amphiphilic( binary- loving) phospholipid motes.
- Integral proteins, the second most critical issue of plasma membranes, are completely incorporated into the membrane shape, with their hydrophobic membrane-spanning sections interacting with the phospholipid bilayer's hydrophobic region.
- Carbohydrates, the1/3 primary issue of plasma membranes, are constantly determined at the outside of cells, connected to proteins( forming glycoproteins) or lipids( forming glycolipids). membrane's composition as a mosaic of factors, including phospholipids, cholesterol, proteins, and carbohydrates, that give it a fluid appearance.
- The membrane's main fabric is made up of amphiphilic( binary- loving) phospholipid motes.
- Integral proteins, the second most important component of plasma membranes, are entirely integrated into the membrane structure, with their hydrophobic membrane-spanning sections interacting with the phospholipid bilayer's hydrophobic region.
- Carbohydrates, the third major element of plasma membranes, are always set up on the outside of cells, associated to proteins( forming glycoproteins) or lipids( forming glycolipids).
