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)
