Question

The plasma membrane consists mainly of

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

Answer 1

The correct option is C Proteins embedded in a phospholipid bilayer

Plasma membrane is the outer covering of animal cells and in plant cells, it is present below the cell wall, protects the cell from its surroundings. It is composed of a phospholipid bilayer with embedded proteins. Plasma membrane plays an important role in cellular processes like cell adhesion, ion conductivity and cell signaling and serve as the attachment surface for several extracellular structures, including the cell wall, glycocalyx, and intracellular cytoskeleton.

Hence the correct option is C.
