Which form of cell communication is used to communicate within the cell itself and with other cells in direct physical contact?
A)Protein channel (gap junction)
B)Plasma membrane-bound signaling molecules
C)Hormone secretion such as neurotransmitters
D)Extracellular chemical messengers such as ligands

Question

Quizplus · Accepted Answer

Cells communicate in three main ways; they display plasma membrane-bound signaling molecules that affect the cell itself and other cells in direct physical contact with it, they affect receptor proteins inside the target cell, and they form protein channels (gap junctions) that directly coordinate the activities of adjacent cells. Neurotransmitters are released by neurons and cross the synaptic cleft to communicate with the cells they innervate. Ligands are involved in binding processes.
