Question

For a regular neuron, the Nernst potential of K+ is about -90 mV. If a researcher applies a drug that binds to and blocks 50% of K+ leak channels, what will the new Nernst potential of K+ be?
1. 0 mV
2. -45 mV
3. -90 mV
4. -135 mV
5. -180 mV

Answer 1

Answer:

2.-45 mV is the answer

Explanation:

because 50% are block by a drug

Answer 2

Answer:

For a regular neuron, the nernst potential of K+ after blocking 50 percent channel will be -45 mv.

Explanation:

It will lessen the resting film potential, making the cell more positive (or increasingly positive).

The estimation of the balance potential for any particle relies on the fixation inclination for that particle over the film. On the off chance that the fixations on the different sides were equivalent, the power of the focus angle would be zero, and the harmony potential would likewise be zero. The bigger the focus slope, the bigger is the balance potential. The balance potential for any particle can be determined utilizing the alleged Nernst potential.
