The following questions refer to comparative concentrations, permeabilities, and potentials under various circumstances. Match the relationship between the two items, A. and B.., with the qualifications labelled a. through c. (Options may be used more than once or not at all.)
-a.concentration of A- in the extracellular fluid
B.concentration of A- in the intracellular fluid of a resting nerve cell
A)A is greater than B
B)B is greater than A
C)A and B are equal

Question

Quizplus · Accepted Answer

B is greater than A because, typically, the concentration of ions like A- (assuming it's a negatively charged ion such as chloride or potassium) is higher inside cells than in the extracellular fluid, especially in the context of resting nerve cells where ion gradients are maintained by active transport mechanisms like the sodium-potassium pump.
