The Intracellular compartment is consist mainly of which of the following electrolytes? aNa, Ca, & CHON bCl, Mg, & CHON cK, Ph, & Mg dK, Ph, & CHO

To determine which electrolytes predominantly make up the intracellular compartment, we first need to analyze the common electrolytes found within cells.

1. Defining Intracellular Electrolytes: The intracellular fluid (ICF) is generally rich in specific electrolytes that are crucial for various cellular processes. The most notable of these include potassium (K⁺), magnesium (Mg²⁺), and phosphates (often represented as HPO₄²⁻ or similar).

2. Evaluating the Options:

   • a. Na, Ca, & CHON: Sodium (Na) and calcium (Ca) are typically found in higher concentrations extracellularly.
   • b. Cl, Mg, & CHON: Chloride (Cl) is mostly extracellular, even though magnesium (Mg) is intracellular.
   • c. K, Ph, & Mg: Potassium (K) is the primary cation in the intracellular fluid, phosphates (Ph) are abundant, and magnesium (Mg) is also present.
   • d. K, Ph, & CHO: Contains potassium and phosphates but CHO (Carbohydrates) are not electrolytes.

3. Final Decision: Assessing the above options, option c stands out as it includes potassium, phosphates, and magnesium, which are all significant components of the intracellular environment.

Final Answer

c. K, Ph, & Mg
