Multiple Choice

What would happen if plasminogen was activated before clot retraction?

Clot retraction would be completed even faster.

Fibrinolysis would occur too early & the healing process could be interrupted.

There would be no significant effect.

Verified step by step guidance

Understand the role of plasminogen: Plasminogen is an inactive precursor of plasmin, an enzyme that breaks down fibrin clots in a process called fibrinolysis.

Recognize the timing of clot retraction: Clot retraction is a process that occurs after a clot has formed, where the clot contracts to reduce its size and bring the edges of the wound closer together.

Consider the sequence of events: Normally, clot retraction occurs before fibrinolysis to ensure that the clot has stabilized the wound and allowed for initial healing.

Analyze the effect of early plasminogen activation: If plasminogen is activated too early, fibrinolysis would begin before the clot has had a chance to retract and stabilize the wound.

Conclude the potential outcome: Early fibrinolysis could lead to premature breakdown of the clot, potentially interrupting the healing process and leading to complications in wound healing.
