- Ca$^{++}$
- Mn$^{++}$
- Mg$^{++}$
- Na$^{++}$
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding blood clotting.
Blood clotting is a complex enzymatic cascade involving several clotting factors.
Step 2: Role of calcium ions.
Calcium ions are essential cofactors for prothrombinase to convert prothrombin into thrombin.
Step 3: Conclusion.
Thus, the correct answer is (A) Ca$^{++$}.
