D)stretch-gated channel and voltage-gated channel

Question

Quizplus · Accepted Answer

Stereocilia are hair-like structures that are found in the inner ear, which are responsible for hearing and balance. These structures contain stretch-gated ion channels that are activated by mechanical stimuli, such as the movement of the head or the bending of the stereocilia. These stretch-gated channels allow for the movement of ions into and out of the stereocilia, which is necessary for the transmission of signals to the brain. Therefore, the best choice for the type of channel associated with ion transport in stereocilia is stretch-gated channel (choice A).
