Example sentences for: permeable
How can you use “permeable” in a sentence? Here are some example sentences to help you improve your vocabulary:
Early in the process the outer membrane becomes permeable, without rupture (Although this is controversial [ 27 ] .), to several proteins found in the mitochondrial inner membrane space including cytochrome c, in which contact sites have a probable role [ 28 ] . During this early phase, though, the inner membrane remains intact and mitochondria still retain their protein import machinery [ 29 ] . Later in the process there is swelling and herniation of the matrix leading to a distension of the cristae [ 8 30 ] .
Glutamate binding to non-NMDA receptors opens ion channels more permeable to sodium (Na +) and potassium (K +) than calcium (Ca 2+).
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.
For the P2X receptor it has been suggested that the Ca 2+-permeable channels grow in size to form the dye-permeable pores through either aggregation of channel subunits or through dilation of the existing channel pore structure [ 12, 18, 19, 20, 21].
Kinetic analysis of Ca transport across Caco-2 monolayers grown on permeable filter supports indicated that 1,25-dihydroxyvitamin D treatment increased the V max of Ca transport [ 17 ] , which would be consistent with a vitamin D-dependent increase in the number of calcium transporters.
