Your question: What statement describes the fluid mosaic model?

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.

Which statement describes the fluid mosaic model quizlet?

Which statement describes the fluid mosaic model? a phospholipid bilayer with various molecules embedded within and floating between the layers. Facilitated diffusion is a protein‑facilitated movement of solutes across a membrane from an area of higher concentration to an area of lower concentration.

Who describe fluid mosaic model?

The fluid mosaic model was first proposed by S.J. Singer and Garth L. Nicolson in 1972 to explain the structure of the plasma membrane.

Why is it described as a fluid mosaic?

It is fluid because it is flexible due to different quantities of cholesterol within the membrane. The mosaic structure refers to the varied composition of the molecules that includes phospholipids as well an array of different structural and functional proteins, carbohydrates and lipids.

Which statement best describes the plasma membrane?

Which statement best describes the plasma membrane of a living plant cell? It selectively regulates the passage of substances into and out of the cell. This is also known as the cell membrane.

Why is the cell membrane described as a fluid mosaic quizlet?

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 describes the fluid mosaic model of the plasma membrane structure?

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.

Which of the following statements best describes the fluid mosaic model of the structure of the cell membrane?

Which of the following statements best describes the fluid mosaic model of the plasma membrane? right answer feedback: The fluid mosaic model of the plasma membrane is composed of two layers of lipid molecules with protein molecules dispersed within.

Which statement best describes how cholesterol affects cell membrane fluidity?

Which statement best describes how cholesterol affects cell membrane fluidity? Cholesterol decreases fluidity at high temperatures (due to increased Van der Waals forces) and increases fluidity at low temperatures (due to decreased Van der Waals forces).

Why is fluid mosaic model considered as the best model?

The lipid bilayer gives fluidity and elasticity to the membrane. Small amounts of carbohydrates are also found in the cell membrane. … The fluid mosaic model is the most acceptable model of the plasma membrane. Its main function is to separate the contents of the cell from the outside.

What is Mosaic in fluid mosaic model?

The fluid mosaic model is a way of describing the structure of cell membranes. The model likens the membrane to a “mosaic” of different components, consisting of a fluid or elastic double layer made up of lipid molecules and large protein molecules. … It is a foundation of understanding cell structures.

Why is the fluid mosaic model of the cell membrane regarded as a dynamic model?

The fluid mosaic model incorporates the dynamic nature of bilayer membrane organization that occurs due to the constant rotational and lateral motion of the integral lipid and protein molecules.

Which statement best describes the role of cell membrane in this model?

Which statement best describes the role of the cell membrane in this model? The cell membrane is an impermeable barrier that prevents water from entering the cell. The cell membrane allows solutes to enter the cell, which causes the cell to shrink.

Which of the following best describes a plasma cell?

Which of the following choices best describes a plasma cell? It is a differentiated B cell. Which of the following distinguishes the secondary immune response from the primary immune response? The secondary response produces higher levels of antibodies.

Which of the following statements is not true about the plasma membrane?

Carbohydrates are never found in plasma membrane is not true. The biochemical investigation done on cell membrane clearly demonstrate that the cell membrane possess protein and carbohydrates as biochemical components. Plasma membrane is present in both plant and animal cells.
