Question

multiple choice question
one activated molecule of factor xii at the start of the intrinsic pathway produces how many fibrin molecules?

hundreds
thousands to millions
very few

Explanation:

The intrinsic pathway of coagulation involves a cascade of enzymatic reactions, where each activated enzyme molecule can activate many molecules of the next enzyme in the pathway, leading to a large amplification. This amplification results in one activated factor XII molecule producing thousands to millions of fibrin molecules.

Answer:

B. Thousands to millions
