Proteins found in the blood respond to blood vessel damage by clumping together forming a clot that physically blocks the hole in the vessel and preventing further blood loss. If clotting proteins were active all the time, they would create clots throughout your circulatory system. Which of the following would be the most efficient way for the body to regulate the expression of the proteins involved in clotting?

Question

Quizplus · Accepted Answer

Producing and storing clotting proteins in an inactive form that can be activated when needed is the most efficient way for the body to regulate the expression of clotting proteins. This allows for a rapid response to blood vessel damage without the risk of forming clots unnecessarily. Option B may work, but it would require constant repression and activation of clotting genes, which would be less efficient. Option C would prevent clotting protein expression altogether, which would be dangerous in the event of blood vessel damage. Option D would still result in the constant production of clotting proteins, which could lead to unnecessary clotting.
