Questions and Answers

What is the function of the lipid bilayer in the cell membrane?

  • Provides receptors for hormones and biologically active substances
  • Facilitates cell-to-cell recognition and adhesion
  • Participates in the electrical events in nerve and muscle cells
  • Serves as a semipermeable barrier (correct)

Where are peripheral proteins located in the cell membrane?

  • Aiding in the regulation of cell growth and proliferation
  • Participating in cell-to-cell recognition and adhesion
  • Spanning the entire lipid bilayer
  • Bound to one or the other side of the membrane (correct)

What is the role of the glycocalyx in the cell membrane?

  • Provides receptors for hormones and biologically active substances
  • Participates in the electrical events in nerve and muscle cells
  • Facilitates cell-to-cell recognition and adhesion (correct)
  • Serves as a semipermeable barrier
