Digestive hormones, enzymes and secretions

Chymotrypsin

Is also a protease released by the Pancreas that works on different amino acids than trypsin.

Remember

Enzymes that break down proteins would possibly break down the protein organs that make them so they must be released in inactive forms. Food and other substances in the GI tract must activate them. This applies to pepsin(stomach), trypsin and chymotrypsin (pancreas). The inactive forms end in the letters ogen

Multiple Choice

Chymotrypsinogen is able to break down protein.

• true

• false

Multiple Choice

which protease begins the breakdown of protein in the stomach?

• trypsin

• chymotrypsin

• pepsin

• all of these

Multiple Choice

Trypsinogen is released by the pancreas and is activated in the intestine.

• true

• false

​Hydrochloric acid released by parietal cells in the stomach activates pepsinogen to become pepsin. Enterokinase released in the small intestine activates trypsin. Trypsin then activates chymotrypsinogen.
