Active proton pump on the pollen grain membrane drives H+ efflux, hyperpolarize the membrane and triggers signaling transduction. 花粉细胞质膜上存在质子泵,由其活化导致的H+外流可以影响细胞膜电位,引发一系列信号转导过程。
So, with low potassium in the blood, the membrane potential can hyperpolarize, or become more negative.
因此,血中低钾时,膜电位会超极化或者说变得更负。

But an inhibitory neurotransmitter hyperpolarizes the postsynaptic neuron by making the inside more negative, driving its charge down — away from its threshold.
但是抑制性神经递质通过使内部更负,使其电荷下降——远离阈值,从而使突触后神经元超极化。

" Equal rights for everybody, an opportunity for them to be able to be here legally." Immigration was becoming a hyperpolarizing issue.
