Which sentence best describes the fluid mosaic model?
D is correct. The Fluid Mosaic Model describes the liquid-like movement of the lipids, proteins, and carbohydrates that make up the plasma membrane. These components travel freely across its surface. 3.
Which of these correctly describes the fluid mosaic model and the part of the cell to which it applies?
Which of these correctly describes the fluid mosaic model and the part of the cell to which it applies? Possible Answers: The fluid mosaic model states that lipids and proteins are embedded in the phospholipid bilayer in a mosaic-like pattern; this applies to the cell membrane.
Why is it described as a fluid mosaic?
Explanation: It is sometimes referred to as a fluid mosaic because it has many types of molecules which float along the lipids due to the many types of molecules that make up the cell membrane. … The liquid part is the lipid bilayer which floats along the lipids due to the many types of molecules that make up the cell.
What best describes the fluid mosaic model of the plasma membrane?
The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. … The proportions of proteins, lipids, and carbohydrates in the plasma membrane vary with cell type.
Who proposed fluid mosaic model?
The fluid mosaic hypothesis was formulated by Singer and Nicolson in the early 1970s . According to this model, membranes are made up of lipids, proteins and carbohydrates (Figure 1).
What is Phosphoglycerides 11?
Lipids that have a phosphate group attached to a diglyceride is called phospholipids. Know that phospholipids that are derived from glycerides are called phosphoglycerides. It contains a phosphate group attached to a glycerol molecule which is esterified with a fatty acid.
