Explain why increasing extracellular k+ reduces the net diffusion of k+ out of the neuron through the k+ leak channels.

Increasing the extracellular potassium ions reduces the net diffusion of potassium ions out of the neuron through the potassium ions leak channels because the concentration of the extracellular potassium ions is high that would cause it to create an obstacle for potassium ions from diffusing out the cell membrane.

Increasing extracellular k+ reduces the net diffusion of k+ out of the neuron

because increasing the extracellular k+ reduces the steepness of the

concentration gradient and so less potassium(k+) diffuses out of the neuron.

Diffusion involves the movement of molecules from region of higher

concentration to that of lower concentration.Changes in the concentration of

the particles involved affects the gradient.

In this scenario, extracellular k+ concentration was increased which reduced the steepness of the concentration gradient . Diffusion involves movement from regions of higher to lower concentration which translates to a reduction in the amount of potassium diffusing out.
