Components of blood
Biology · Secondary 3 · Medium · Components of blood
Blood clotting involves the conversion of fibrinogen to fibrin. This reaction is catalysed by the enzyme thrombin. In a patient with low calcium ion levels, how will blood clotting be affected?
- Clotting will be slower because less thrombin is formed to convert fibrinogen to fibrin.
- Clotting will be faster because less fibrin is needed to form a clot.
- Clotting will be unchanged because calcium ions are not involved in the process.
- Clotting will not occur at all because platelets cannot be produced without calcium.
