When two action potentials arrive in close succession to deliver excitatory neurotransmitters to the attached neuron, the result will beQuestion 12Select one:a.addition of the end plate potentials to give rise to action potentialb.addition of end plate potentials to give rise to hyperpolarizationc.resting potential

The correct answer is a. Addition of the end plate potentials to give rise to action potential.

Here's why:

When two action potentials arrive in close succession, they deliver excitatory neurotransmitters to the attached neuron. These neurotransmitters bind to the receptors on the neuron, causing an influx of positive ions into the neuron. This influx of positive ions causes the neuron's membrane potential to become more positive, a process known as depolarization.

If the depolarization reaches a certain threshold, it triggers an action potential, which is an electrical signal that travels down the neuron. This process is known as summation, and it involves the addition of end plate potentials (the potentials created by the neurotransmitters binding to the receptors) to give rise to an action potential.

Therefore, the result of two action potentials arriving in close succession is not hyperpolarization (which would make the neuron less likely to fire an action potential) or resting potential (the neuron's baseline state when it's not firing an action potential). Instead, the result is the addition of end plate potentials to give rise to an action potential.
