Why is the membrane described as a fluid mosaic quizlet?

Why is the plasma membrane described as a fluid mosaic 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 cell membrane sometimes referred to as a fluid mosaic what part of the cell membrane Actslike a fluid and what makes it like a mosaic?

What part of the cell membrane acts like a fluid? And what makes it a mosaic? It is sometimes referred to as a fluid mosaic because it resembles an artistic mosaic due to its many different molecules that it contains. The part that acts like a fluid is the lipid bilayer.

What is the fluid mosaic model quizlet?

Fluid Mosaic Model. A model that refers to how the lipid bilayer tends to act more like a liquid than a solid and contains a number of different components. Glycolipid. Phospholipid with an attached sugar chain. Glycoprotein.

Why is the cell membrane described as selectively permeable quizlet?

The cell membrane is said to be selectively permeable because it lets certain substances pass through while restricting the passage of others.

Why is the plasma membrane referred to 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. For example , there are a lot of types of proteins embedded in the membrane.

Which best describes the permeability of a membrane?

Permeability is the condition of being capable of having materials flow into and out of a membrane. The permeability of a cell membrane is determined by how easily a molecule can diffuse across the membrane. Usually, only molecules that are fat-soluble can permeate across a cell membrane.

Why is it important for cell membrane to be fluid?

Fluidity is important for many reasons: 1. it allows membrane proteins rapidly in the plane of bilayer. 2. It permits membrane lipids and proteins to diffuse from sites where they are inserted into bilayer after their synthesis.

Why does the cell membrane need to be fluid?

Explanation: Cell membrane is fluid because individual phospholipid molecules and proteins can diffuse within their monolayer and thus move around. The fluidity is affected by: The length of the fatty acid chain.
