Most cells are in physical contact with other cells at all times by forming permanent connections called
A)cell junctions.
B)gated ion channels.
C)enzymatic receptors.
D)G-protein-coupled receptors.
E)cell surface markers.

Question

Quizplus · Accepted Answer

Cell junctions are direct physical connections between adjacent cells that keep them in contact with each other. They are involved in cell-to-cell communication, regulation of tissue architecture, and maintenance of cellular integrity. Gated ion channels, enzymatic receptors, G-protein-coupled receptors, and cell surface markers are different types of membrane proteins that are involved in signaling and recognition processes but do not necessarily form permanent connections between cells.
