Question

Scientific research has shown there are at least four different types of phospholipids in cell membranes. Which of the following BEST explains these variations?

When the membranes are exposed to environmental differences, specific genes are turned on and off.

Mutations in the phospholipid membranes have altered the membrane structure but not their function.

Different types of the same basic structure of membranes provide the cell with a wider range of functions.

When translation and transcription errors cause slight amino acid differences in the membrane, the same basic structure has slight variations.

Answer 1

Different types of the same basic structure of membranes provide the cell with a wider range of functions.

The cell membrane consist of bilayer of the phospholipid with the protein.The phospholipid is the amphipathic molecule contains two fatty acid chain which is hydrophobic in nature links the phosphate hydrophillic group.The phospholipid bilayer forms the basic structure for all the cellular membrane and forms the stable block between two aqueous compartments and provides various functions.
