The resting membrane potential exists because: • Cytoplasm has different chemical and ionic compositions from ECF; • Plasma membranes have selectively permeability. Potential rises and falls due to temporary permeability changes. Opening or closing membrane channels causes changes in membrane potential...
The membrane potential (pd) of duck weed (Lemna gibba G1) proved to be energy dependent. At high internal ATP levels of 74 to 105 nmol ATP g-1 FW, pd was between -175 and -265 mV. At low ATP levels of 23 to 46 nmol ATP g-1 FW, pd was low, about -90 to -120 mV at pH...
The changes of membrane potential were accompanied by synaptic activity. Synaptic activity plays an important role in the information transmission and regulation of the nervous system, which is the basis of maintaining the function of the nervous system.()A、对B、错 相关知识点: 试题来源: 解析...
This brief review has tried to shed some light on the mechanisms and significance of the changes in membrane potential and in ionic fluxes occurring in B-cells upon glucose stimulation. There is now strong evidence that, under physiological conditions at least, these electrical events-and the unde...

This shows that capsaicin-induced release of neuropeptides from sensory afferents is not dependent on membrane potential changes, and that capsaicin-induced Ca 2+-influx into nerve terminals does not require activation of voltage-sensitive calcium channels (VSCC). On the other hand, in the ...

Do Ion Concentrations Change When the Vm Changes? A logical question to ask regards whether the efflux of K+ and influx of Na+ that occurs to establish the resting membrane potential changes the concentration gradients. Similarly with changes in Vm, such as action potentials and synaptic potential...
