MscS and MscL are Mechanosensitive Channels That

Question

MscS and MscL are mechanosensitive channels that ...
A) constitute the majority of channel proteins in the plasma membrane of auditory hair cells in the human cochlea.
B) open in response to membrane tension.
C) open at the same osmotic pressure, but differ in their ion selectivity.
D) are highly ion selective.
E) All of the above.

Accepted Answer

The mechanosensitive channels of small and large conductance (MscS and MscL) in bacteria open to form relatively nonselective pores of different sizes when the osmotic pressure increases to moderate and high levels, respectively.
