Which two electrolytes are involved in blood coagulation?

Explanation:
The main idea is that coagulation depends on divalent cations that act as cofactors for enzyme complexes and for proper assembly on phospholipid surfaces. Calcium ions are essential in this process; they enable multiple steps in both the intrinsic and extrinsic pathways, including the formation of the prothrombinase complex and the activation of vitamin K–dependent clotting factors. Magnesium, another divalent cation, provides a supporting role as a cofactor for several enzymes and helps stabilize interactions on phospholipid surfaces, contributing to coagulation efficiency. The other electrolytes listed do not have direct roles in driving the coagulation cascade, so the combination of calcium and magnesium best fits the requirement for electrolytes involved in blood coagulation.
