Question

1.What are the three receptors that we discussed sensitive to? Like, how are they activated? Also, what do they allow in and out?

2.Sodium leak channels leak sodium in which direction? Into the cell or out of the cell?

3.Potassium leak channel leak K+ which direction?

4.The “potential” that travels down the axon is called...

Answer 1

1. Incomplete information is given.

2.Sodium leak channels leak sodium into the cell. This is because concentration of the sodium is higher outside than inside the cell allowing the sodium to diffuse into the cell though sodium leak channels

3.Potassium leak channels leak potassium out of the cell. This is because concentration of the potassium is higher inside than outside the cell allowing the sodium to diffuse out of the cell though potassiumleak channels

4.The “potential” that travels down the axon is called is called Action potential of the neuron.
