Final answer:
When you increase the threshold required to generate an action potential, a stronger stimulus is needed to trigger the action potential. This does not result in a bigger action potential, but it might require a stronger stimulus to initiate multiple action potentials more quickly.
Step-by-step explanation:
An action potential is an electrical signal that is generated by a neuron when it receives a strong enough stimulus. When the threshold required to generate an action potential is increased, it means that a stronger stimulus is needed to depolarize the membrane and trigger the action potential.
The action potential itself is an all-or-none event, meaning that it either happens completely if the threshold is reached, or it does not happen at all if the threshold is not reached. Increasing the threshold does not result in a bigger action potential, but it may require a stronger stimulus to initiate multiple action potentials more quickly.
