In this reaction, all reactants and products are invisible. The heat being evolved is the clue that tells you a reaction is taking place. This is a good example of an exothermic reaction, a reaction in which heat is given off. A lot of reactions are exothermic.
Prothrombinase will cleave prothrombin to make thrombin and thrombin is the enzyme that cuts fibrinogen to make fibrin for clot formation [Blood Clotting: The Basics]. The platelet prothrombinase activity is the same as the activity on TP-bearing cells: itâs formed from Xa and membrane-bound Va.
Protease inhibitors are antiviral drugs. They interrupt the way HIV uses a healthy cell to make more virus. When HIV enters a healthy cell, its only goal is to make more viruses to infect other healthy cells.It does this by making the cell produce certain proteins the virus can use to copy itself.Two of the proteins used by the virus are reverse transcriptase and protease. The goal of the protease inhibitor is to stop the protease from helping to assemble a new virus.The diagram above shows the virus entering the cell (1), the cell making new proteins (2-3), the proteins forming a new virus (4) and the cell releasing the new virus to infect other cells (5).t does this by making the cell produce certain proteins the virus can use to copy itself. Two of the proteins used by the virus are reverse transcriptase and protease. The goal of the protease inhibitor is to stop the protease from helping to assemble a new virus.
