Pathogenic microbe produces a toxin which blocks the Na+ leak channels

A newly discovered pathogenic microbe produces a toxin which blocks the Na+ leak channels. Choose the condition which would be induced by exposure to this type of toxin. 0 Neuron conducts action potentials normally, but does not transmit these potentials across synapses. 0 Rapid depolarisation at threshold potential does not occur. 0 Rapid depolarisation of the membrane at threshold potential occurs, but does not repolarise immediately afterwards. O No membrane potential observed (i.e., measures at 0 mV). 0 The neuron becomes hyperpolarised (resting potential decreases below
