Imagine a neuron with no dendrites and 1m axon. The distance between nodes of Ranvier 1mm. Cell body diameter 20 um. Axon internal diameter 10um. Assume normal concentration of potassium and sodium: [K] inside=140mm; [K+Joutside=4mM; [Na]mside=15mM; [Na]outside=150mM; 1. Approximate membrane potential at equilibrium when K+ permeability is infinitely greater than Na' permeability?​

When the solution concentration on the outside of a cell is greater than thesolution concentrate on the inside of the cell, what type of solution is the cellwithin?

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. oxygen will diffuse more quickly into cell because . b the oxygen molecules inside cell b have a higher kinetic energy b. a its membrane transport proteins will not be saturated c. a the diffusion gradient there is shallowerd. b the diffusion gradient there is steeper
