And we'll see how that happens in just a moment. First, let's actually discuss where the Chimotrypcinogen is formed. So if we study the pancreas of our body, in the pancreas, we're going to find these special cells, exercise cells known as acinor cells. And it's the asinr cells of the pancreas which are responsible for forming this Chimetrypcinogen, as well as other digestive zymogens. And all these Xiaomogens are essentially stored in membrane bound organelles, in membrane bound granules shown in green. And so all these granules that contain the zymogens basically accumulate on the apex side of these asinr cells.
