Which statement best describes electrolytes?

• A. These are charged particles that conduct an electrical current and help regulate body functions.
• B. They are large proteins that transport oxygen in blood.
• C. They are carbohydrates used for energy.
• D. They are cells that fight infection.

Answer: (A)

Electrolytes are minerals that dissolve in body fluids to form charged particles (ions) such as sodium, potassium, and chloride. These ions conduct electrical currents, which is essential for nerve signaling, muscle contractions (including the heart), and regulating fluid balance and pH. That’s why the statement describing electrolytes as charged particles that conduct an electrical current and help regulate body functions is the best description. The other options point to proteins that transport oxygen, carbohydrates used for energy, and cells that fight infection, which are not electrolytes.
