Rennin + Angiotensinogen = Angiotensin-I
But this newly emerging molecule has no effect, because the chain of
production is not yet complete. An enzyme by the name of ACE, found in
the lungs and serving solely to break down the angiotensin-I molecule,
now enters the equation. Thanks to this enzyme, angiotensin-I turns into
yet a different molecule, angiotensin-II (Figure 43).
Angiotensin-I + the ACE enzyme = Angiotensin-
II
Once again, we need to step back and reflect. Two different molecules
produced by the kidney and liver cells have combined with each other, and
a new molecule has emerged. Lung cells, which are totally unconnected to
the kidney and liver cells, produce another enzyme that will perfectly at-
tach to this new molecule. In addition, they produce this enzyme long be-
fore the molecules in question have combined together. But how do lung
cells produce the most appropriate enzyme for an event that has not yet

The enzyme ACE turns angiotensin I into yet a
different molecule, angiotensin II.
