Example sentences for: permeable
How can you use “permeable” in a sentence? Here are some example sentences to help you improve your vocabulary:
This occurs, not by release of Ca 2+from internal stores, but rather from activation of a ubiquitously-expressed, non-selective, Ca 2+-permeable cation channel (CaNSC), present in the plasmalemma [ 2, 3, 4, 5, 6, 7, 8].
The initial MTX-induced increase in [Ca 2+] i reflects the activation of a Ca 2+-permeable non-selective cation channel (CaNSC) [ 1 4 5 6 7 8 ] . This channel, which has a reported conductance in the range of 12-40 pS depending on ionic conditions [ 5 9 10 11 ] , causes rapid membrane depolarization, which in excitable cells, leads to activation of voltage-sensitive channels.
They are constitutively permeable to water, and also function as regulated non-selective cation channels [ 10 ] when gated by intracellular cyclic GMP [ 11 12 ] . Even though only a small proportion of the AQP1 channels that are present in the membrane appear to be available for cGMP-activation of the ionic conductance (1/56,000), model-based calculations nonetheless suggest that this contribution could be meaningful in a physiological setting [ 13 ] . Unlike transporters which move substantial amounts of substrate by design, ion channels function to change membrane potential by the net movement of relatively tiny amounts of charge (~10 picomoles per cm 2membrane to generate a change of 100 mV) [ 14 ] , hence the low proportion of active AQP1 ion channels is consistent with a functional goal of gated ionic signaling that is distinct from that of massive constitutive osmotic water permeability.
as if the circuit of the city wall were a permeable membrane admitting the wilderness inside, wild and tame inter- penetrating,
In contrast to the non-NMDA receptors, the high conductance channel associated with the NMDA receptors is permeable to Ca 2+as well as to Na +and K +. Also NMDA-gated currents typically have slower kinetics than kainate- and AMPA-gated channels [ 3].
