Question

1. Why can't a typical cell have as many Na+ leak channels as K+ leak channels?

Answer 1

Answer: Because the typical cell want to maintain resting membrane potential, which is negative many times, inside the cell more K+ ion instead of Na so cell is superpermeable to K+ and partial permeable to Na+.

Leakage channel is a ion channel in a cell membrane that is always open and that makes the membrane ion-permeable.These channels are found in the plasma membrane or cell mebrane of almost all animal cells.

Leakage channels are K+ Leak channel and Na+ Leak channel.

Typical cell have more K+ Leak channels as compared to  Na+ Channels.

One of the major components that maintains the membrane potential in animal cells is the potassium leak channel.

The cell has channels of potassium and sodium leakage which allow the two cations to diffuse their concentration gradient downwards. Neurons, though, have far more channels for potassium leakage than channels for sodium leakage. Potassium therefore diffuses from the cell at a much faster rate than sodium leaks in. The disparity in electric charge on each side of a membrane produces a membrane potential. The sodium-potassium pump and the diffusion of K+ ions through the potassium leak channel are responsible for this difference in electrical potential.
