What best explains the relationship between structure and function of the cell membrane?

Question

• The single-layer membrane surrounding the outside of the cell allows for the easy removal of waste.
• The lipids and proteins that make up the membrane allow it to be selective about what enters and leaves the cell.
• The fluid inside the membrane buffers the chemical reactions taking place inside the cell.
• The lipids forming the membrane provide energy for protein synthesis.

Answer 1

The option that best explains the relationship between structure and function of the cell membrane is:

"The lipids and proteins that make up the membrane allow it to be selective about what enters and leaves the cell."

This statement highlights how the unique structure of the cell membrane, composed of a phospholipid bilayer with embedded proteins, contributes to its function. The lipid bilayer creates a semi-permeable barrier, while the proteins facilitate selective transport and communication with the environment, allowing the cell to regulate its internal composition effectively.
