Question

What is the effect of enzyme coagulase on plasma?

1) It causes coagulation in plasma
2) It causes agglutination in plasma
3) It has no effect on plasma
4) Cannot be determined

Answer 1

Coagulase, mostly from Staphylococcus aureus, induces blood clot formation by converting fibrinogen into fibrin, creating a protective mesh around the bacteria against the immune system. This enzymatic activity distorts the natural clotting process, potentially leading to pathological conditions and highlighting the intricate balance within blood coagulation mechanisms.

Step-by-step explanation:

The effect of the enzyme coagulase on plasma is specifically related to the coagulation process. Coagulase, produced by certain bacteria like Staphylococcus aureus, can manipulate the blood's clotting mechanism to its advantage. Normally, blood clotting occurs in response to vascular injury, where fibrinogen converts to fibrin, creating a mesh that traps blood cells and forms a clot to prevent blood loss. However, when coagulase enters the bloodstream, it artificially initiates this process without vessel damage, leading to the clotting of blood. The resulting fibrin mesh coats the bacteria, protecting them from the immune system's phagocytic cells. This activity is crucial for bacterial infections and their ability to evade host defences. In a broader context, if an imbalance occurs in coagulation-related enzymes synthesized in the liver, it may indicate liver dysfunction, which could be a concerning health issue. Contrasting with coagulase, kinases break down clots, and other elements like calcium ions are pivotal in blood clotting, being the target of certain anticoagulants.

Overall, coagulase alters the normal hemostatic process, exploiting it to shield bacteria from immune responses, which can lead to a pathological state in the host. This raises concerns over the delicate balance of coagulation and how pathogens may disrupt it for survival and propagation.

Answer 2

Coagulase causes coagulation in plasma by triggering the blood clotting cascade, resulting in the formation of a mesh that traps blood components, forming a clot to protect bacteria from immune response.

Step-by-step explanation:

The effect of the enzyme coagulase on plasma is that it causes coagulation in plasma. Coagulase is an enzyme produced by some bacteria, such as Staphylococcus aureus, and it manipulates the blood clotting system to protect the bacteria from the immune system.

Normally, the blood clotting process is initiated by damage to blood vessels and involves a cascade of reactions that result in the conversion of fibrinogen into fibrin. Fibrin forms a mesh that traps platelets and erythrocytes, producing a blood clot. When bacteria release coagulase, they trigger this process without the presence of vessel damage, which results in a clot that can shield them from immune cells. Therefore, the correct answer to the effect of enzyme coagulase on plasma is option 1: It causes coagulation in plasma.
