The coagulation cascade begins when one of these proteins gets proteolytically cleaved.

当这些凝血因子之一被水解裂解时，凝血级联反应就启动了。

The coagulation cascade starts when one of these proteins gets proteolytically cleaved.

当某一个凝血因子被活化即发生蛋白水解反应时，凝血级联过程就开始了。

This active protein then proteolytically cleaves and activates the next clotting factor, and so on.

然后这一活化的凝血因子激活另一个未活化的凝血因子，以此类推。

Procoagulants could be proteins like tissue factor or bacterial components like lipopolysaccharide, or could even be the presence of enzymes that help to proteolytically cleave and activate clotting factors.

促凝因子可以是类似组织因子的蛋白质，或者类似脂多糖的细菌成分，甚至可以是帮助蛋白酶切割和活化凝血因子的酶。
