b. They help in regulating the flow of water across the cell membranes.

c. They also help in transporting sugars and amino acids into the cells.

(B) Importance of Potassium $\left(K\right)$ in biological fluids

Potassium ions are found in the highest quantity within the cell fluids.
a. $K^{+}$ ions help in activating many enzymes.
b. They also participate in oxidizing glucose to produce ATP.
c. They also help in transmitting nerve signals.

(C) Importance of Magnesium $\left(Mg\right)$ in biological fluids

Magnesium referred to as macro-minerals. It has higher abundance in the human body system.

a. $Mg$ helps in relaxing nerves and muscles.

b. $Mg$ helps in building and strengthening bones.

c. $Mg$ maintains normal blood circulation in the human body system.

(D) Importance of Calcium $\left(Ca\right)$ in biological fluids

Calcium referred to as macro-minerals. it has higher abundance in the human body system.

a. $Ca$ helps in the coagulation of blood

b. $Ca$ also helps in maintaining homeostasis.
