試題詳解

15.Transient receptor potential (TRP) channels are sensors for a variety of cellular and environmental signals.TRP channels are responsible for various sensory responses including heat, cold, pain, stress, vision and taste and can be activated by a number of stimuli. TRP channel includesTRPC( "C" for canonical),TRPV("V" for vanilloid),TRPVL("VL" for vanilloid-like),TRPM("M" for melastatin),TRPS("S" for soromelastatin),TRPN("N" for mechanoreceptor potential C), andTRPA("A" for ankyrin),TRPP("P" for polycystic) andTRPML("ML" for mucolipin).下列有關 TRP 離子通道的敘述，哪些正確？
(A)one of cation channels major in plasm membrane
(B)TRPV1is activated bycapsaicin
(C)TRPA1 and TRPM8 are heat receptor
(D)TRP channels are all selective ion channels, not have non-selective channels
(E) TRP channels in vertebrates not in invertebrates
