Why it is important to have calcum ions during the process of blood clotting ? My teacher said i don't really have to know this but iam really curiuos=p
Blood clotting is a very complex matter. I'll try to just summarise the bit concerning calcium ions.
Blood cloting involves a process called
coagualtion. Blood coagulation is a complex biochemical process involving platelets and dozens of proteins. Activation of platelets triggers a multistep "cascade" that produces a "thrombus" or clot.
Calcium is involved at several steps in this cascade, including the activation of the platelets themselves. Coagulation is so dependent on calcium that blood banks routinely add citric acid to banked blood to bind ionized calcium and prevent the product from clotting before it can be used.
I'll advice you to
restrict yourself to the syllabus for the time being. I understand that biology is a very interesting subjects which catches your attention easily and makes you wana know more. I've experienced that feeling myself years ago
But please, keep these things outside the syllabus after you have done with your exams. You'll then have the luxury of making research concerning anything yourself.
