The correct answer is:
d) Electrolytes
1. Electrolytes such as sodium, potassium, and magnesium play a crucial role in regulating cellular processes within the body.
2. These electrolytes are essential for maintaining proper fluid balance, nerve function, muscle contractions, and overall cell function.
3. Sodium helps to regulate water balance, potassium is important for nerve signaling and muscle contractions, and magnesium is involved in energy production and muscle function.
4. Therefore, choosing option d) Electrolytes is the most accurate as fiber, carbohydrates, and vitamins do not primarily regulate cellular processes like electrolytes do.
