Question

Quizplus · Accepted Answer

The intrinsic clotting mechanism is inhibited by the interruption at the Factor IX activation step, as this pathway relies on Factor IX to activate Factor X and ultimately lead to the formation of a stable clot. The other options (A, B, and C) are not directly affected by a lack of Factor IX.
