Question

What would be the effect of the preventing the flow of the potassium ions to the neuron?

• A. Action potentials would be more stronger than usual
• B. The threshold potential of the Neuron would be more negative
• C. The resting potential of the neuron would be more negative
• D. There would be no repolarization during an action potential

Answer 1

The correct option is A Action potentials would be more stronger than usual

• The action potential is a process through which a neuron conducts electrical impulses this is done by the flow of positively charged ions through the neuronal membrane.
• The sodium channels allow the flow of sodium ions and the potassium channels allow the flow of potassium ions.
• This causes depolarization and repolarization of the neuronal membrane which results in the passage of stimuli or electrical impulses from one neuron to other neurons.
• If the potassium ion flow is prevented, then repolarization and depolarization phase of the action potential doesn't take place and hence the impulses will not be transmitted.

So, the correct option is 'Action potential would be more stronger than usual'.
