What is the best description of the fluid mosaic model quizlet?

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 best 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.

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 the phospholipid bilayer is composed of hydrocarbons that are fluid and give the cell flexibility; this applies to the cell membrane.

What does the fluid part of fluid mosaic model mean quizlet?

What part of it makes it a fluid and what part of it makes it a mosaic? … 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 is fluid mosaic model class 11?

Fluid mosaic model of cell membrane was proposed by Singer and Nicolson. According to Fluid mosaic model, the quasi-fluid nature of lipid enables lateral movement of proteins within the overall bilayer, and the ability to move within the membrane is measured as its fluidity.

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.

What is the plasma membrane made of describe it in terms of the fluid mosaic model?

According to the fluid mosaic model, the plasma membrane is a mosaic of components—primarily, phospholipids, cholesterol, and proteins—that move freely and fluidly in the plane of the membrane. … A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.

What statement describes a concentration gradient quizlet?

concentration gradient definition. the process of particles moving through a solution from an area of higher number of particles to an area of lower number of particles.

What describes simple diffusion?

Simple diffusion is the process by which solutes are moved along a concentration gradient in a solution or across a semipermeable membrane. Simple diffusion is carried out by the actions of hydrogen bonds forming between water molecules and solutes.

What does Mosaic mean 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.

What makes the fluid mosaic model the most acceptable model of a membrane?

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.

Which of the following cell parts is described as a fluid mosaic?

Cell-membrane was described by the “fluid mosaic model”. It describes the cell membrane as a two-dimensional liquid that restricts the lateral diffusion of the membrane components.

Why is the model used to describe the plasma membrane called the fluid mosaic model quizlet?

– The plasma membrane is described as a fluid mosaic model because its made up of a phospholipid bilayer, allowing it easily to bend and move along without breaking or ripping the membrane due to the hydrophobic and hydrophilic poles of the bilayer.

Why is the plasma membrane described as fluid?

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.

What is the structural framework of the fluid mosaic model?

In every plasma membrane lies a structural framework of different components with significant cellular functions, making up a mosaic known as the fluid mosaic model. According to this model, the cell membrane represents a fluid structure comprised of proteins within a phospholipid bilayer.
