What Ion Would Have the Fastest Flux Rate in a Resting Neuron?

In a resting neuron with a membrane potential (Vm) of -65 mV, the ion that would have the fastest flux rate is Ion 1 (e1) at 50 mV with 100 channels open. This is because the ion with the highest concentration gradient and membrane potential will have the fastest flux rate.

In this case, Ion 1 has the highest membrane potential and the largest number of channels open, making it the fastest among the options provided. The concentration gradient, which is determined by the difference in ion concentration inside and outside the neuron, plays a crucial role in ion flux rate.

Therefore, in a resting neuron scenario, where the membrane potential is -65 mV, Ion 1 (e1) at 50 mV with 100 channels open would show the fastest flux rate due to its favorable concentration gradient and membrane potential combination.
