Explanation:

Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.

They are important because:

1. Validate a direct binding assay

2. Confirm whether or not a drug binds to the receptor

3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects

During the action potential of a neuron, which ion is primarily crossing the membrane during the depolarization phase, and in wh
iragen [17]
The answer is Na + is entering the cell and the K + is leaving, during the depolarization phase of the action potential open Na + channels allow Na + ions to diffuse into the cell. This inward movement of positive charge makes the membrane potential more positive. The depolarization phase is a positive response sequence where open Na + channels cause depolarization which in re-occurrence causes more voltage gated Na+ channels to open.
