Title: What mechanism causes hair cell depolarization as stereocilia bend in response t Post by: jfad21 on Nov 1, 2014 What mechanism causes hair cell depolarization as stereocilia bend in response to sound waves?
a.Otoliths shift to open ion channels and depolarize hair cells. b.Receptor cells release ATP. Neighboring cells take up the ATP to generate action potentials. c.Tip links open ion channels, which causes membrane depolarization. d.Rhodopsin absorbs energy to cause an increase in cGMP that opens cyclic nucleotide-gated channels.
