So basically, once in the bloodstream, renan goes on to activate the Xymogen angiotensinogen into angiotensin one by cleaving it proteollytically at a specific specific position along the amino acid sequence. Angiotensinogen is produced inside our liver cells. Now, once we activate the angiotensin one, it basically goes on, travels through our blood system and eventually ends up at lung cells as well as in our kidney cells. And once it's found in those cells, the cells basically contain a special type of enzyme known as ace, which stands for angiotensin converting enzyme. And what that enzyme basically does is it converts angiotensin one into angiotensin II by basically cleaving two residues on that particular enzyme. So angiotensin one hormone then travels to lung cells and kidney cells.
