Pepsin is a digestive protease (EC 3.4.23.1) released by the chief cells in the stomach that functions to degrade food proteins into peptides. From: http://en.wikipedia.org/wiki/Pepsin

Pepsin
Decreased incubation temperature would likely decrease pepsin activity because enzymes generally have optimal temperature ranges for activity, and lower temperatures can slow down enzyme reactions. Pepsin is a digestive enzyme that functions optimally at around body temperature (37°C), so decreasing the temperature may reduce its efficiency in breaking down proteins.
The intestines belong to the Digestive Tract (or Digestive System.) Fact: Stretched from end to end, the human intestines would stretch a mile, literally!
Pepsin activity would decrease and at a very low temperature pepsin would be inactive.
Neither contaminated pepsin nor deionized water would cause the digestion of BAPNA. Pepsin is a digestive enzyme that breaks down proteins, while deionized water is unlikely to impact enzymatic activity. Any digestion of BAPNA would more likely be due to enzyme activity or other factors.
Pepsin activity would decrease and at a very low temperature pepsin would be inactive.
If one of the organs in the digestive system, then.
You would die.
Consider the stomach. The inactive form of the digestive enzyme pepsin is called pepsinogin. ( spelling may be wrong ) It takes the release of hydrochloric acid in the stomach to activate this pre-enzyme into pepsin, the active form. You would be digesting your own stomach tissue if pepsin was always active.
Blood vessels do not carry digestive juices to the digestive system. Digestive juices are either secreted directly into the lumen of the digestive tract, or are carried by ducts, as with bile and pancreatic juice.
The stomach is a part of the digestive system. It is responsible for breaking down food through the secretion of digestive enzymes and acids.
