Question

The plasma membrane consists mainly of

• A. Phospholipids embedded in a protein bilayer
• B. Proteins embedded in a phospholipid bilayer
• C. Proteins embedded in a polymer of glucose molecules
• D. Proteins embedded in a carbohydrate bilayer

Answer 1

The correct option is B Proteins embedded in a phospholipid bilayer

The fluid mosaic model of the plasma membrane explains that that plasma membrane is composed of a fluid bilayer made of phospholipid molecules, with proteins, glycoproteins, glycolipids and cholesterol molecules embedded in the bilayer. Thus this is the right answer.
