AIt is the dominant cation outside cells
BIt is the dominant anion inside cells
CIt is the dominant anion outside cells
DIt is the dominant cation inside cells
Answer & Solution
Correct answer: C. It is the dominant anion outside cells
1. Chloride carries a negative charge, so it is an anion rather than a cation.
2. It travels closely with sodium in the extracellular environment.
3. That association makes it the dominant anion of the extracellular compartment.
4. Its regulation closely mirrors that of sodium, which is why the two are so often handled together.
