What happens after the rise in permeability to Na⁺ in a neuron?
What happens after the rise in permeability to Na⁺ in a neuron?
The permeability to K⁺ increases.
The polarity of the membrane remains unchangeD)
The resting potential of the membrane decreases
The permeability to Na⁺ decreases
Solution
The rise in permeability to Na⁺ is short-lived and is followed by a rise in permeability to K⁺. K⁺ diffuses outside the membrane, restoring the resting potential of the membrane.
