Which of the following mineral ions plays a very important role in the cascade process of blood coagulation?

Step-by-step solution

Blood coagulation occurs through a cascade of complex enzyme-catalyzed reactions. Calcium ions ( Ca⁺⁺ ) play a crucial role in this process. They are required for the activation of several coagulation factors, including the conversion of prothrombin to thrombin and the activation of Factor X. Without calcium ions, the blood clotting process cannot proceed effectively. Answer: Calcium ( Ca⁺⁺ )
