Question

click and drag on elements in order. arrange the sequence of events of an action potential in correct order. instructions. a threshold stimulus causes voltage gated sodium channels to open. voltage gated potassium channels open. potassium diffuses out of the neuron. sodium enters the neuron.

Explanation:

An action potential starts when a threshold stimulus causes voltage - gated sodium channels to open, allowing sodium to enter the neuron. Then, voltage - gated potassium channels open and potassium diffuses out of the neuron.

Answer:

1. A threshold stimulus causes voltage gated sodium channels to open.
2. Sodium enters the neuron.
3. Voltage gated potassium channels open.
4. Potassium diffuses out of the neuron.
