The blue molecules are Zymogen. So basically enzymes in their inactive form, and the red molecules are the active form of enzyme. So purple molecules are proteins, they're not enzymes. The blue molecules are the zymogen form of the enzyme and the red molecules are the active form of that enzyme. So once we have the rupture, we have the exposure of the tissue factor. And basically, once the TF is exposed to the blood plasma, we have this molecule that is activated.
