So our pancreas produces our trypsinogen. And when our interkinase mixes with trypsinogen, it cleaves it and it forms the active form known as trypsin. And trypsin doesn't only cleave peptides at specific peptide buns, but it also activates other enzymes, as we'll see in just a moment. So let's move on to chymo trypsinogen. Chimotrypsinogen is yet another type of peptidase that is produced by the pancreas and Chimotryptinogen is activated by trypsin. So trypsin actually activates chimotryptinogen into chimotrypsin.
