Question

Which of the following is major intracellular cation?

• A. Potassium
• B. Chloride
• C. Phosphate
• D. Calcium

Answer 1

The correct option is A Potassium

• Electrolytes are substances that dissociate in solution and have the ability to conduct an electrical current i.e nerve impulse. These substances are located in the extracellular and intracellular fluid. Within the extracellular fluid, the major cation is sodium and the major anion is chloride. The major cation in the intracellular fluid is potassium. These electrolytes play an important role in maintaining homeostasis.
• Hence potassium is major intracellular cation.
• So, the correct answer is 'Potassium'.
