ACTION POTENTIAL $600 Name the 3 main ions involved in an action potential. Calcium, sodium, potassium

ACTION POTENTIAL $800 What is the SPECIFIC role of calcium in an action potential? It causes the neurotransmitter vesicles to move to the cell edge and undergo exocytosis.

ACTION POTENTIAL $1000 Discuss the relationship between these 3 parts of an ACTION POTENTIAL. Ligand Acetylcholine Sodium Voltage gate Acetylcholine acts as a ligand on the sodium voltage gate. The ligand causes the gate to open and allows Na to flow into the cell beginning the action potential. DAILY DOUBLE
