Question

Which statements about the fluid mosaic structure of a membrane are correct? Select the three correct statements.

1 The framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.2 The diverse proteins found in and attached to membranes perform many important functions.3 The kinky tails of some proteins help keep the membrane fluid by preventing the component molecules from packing solidly together.4 Membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.5 Because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.

Answer 1

1) The framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.

2) The diverse proteins found in and attached to membranes perform many important functions.

5) Because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.

Step-by-step explanation:

Fluid mosaic membrane is made up of lipid bilayer in which membrane phospholipids are assembled in a dual layer. One is hydrophilic head region which is facing to the cytosol and extracellular region made up of phosphate group, another is non-polar hydrophobic tail facing each other and made up of two long chains of fatty acids. These two layer covalently attached to a glycerol molecule.

Fluid mosaic model, the plasma membrane consist mosaic of components such as cholesterol, protein, carbohydrates and phospholipids they give the membrane a fluid characteristic.

Answer 2

The correct statements are:

1. The framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.

2. The diverse proteins found in and attached to membranes perform many important functions.

5. Because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.
