Why does the enzyme trypsin get deactivated when introduced in the gastric juice of the stomach?

- the optimum ph for trypsin is about 8.0, which is the ph of the intestine, whereas the ph of gastric juice is 1.5 - 2.0, which is highly acidic.

- the optimum ph for trypsin is about 2.0, which is the ph of the intestine, whereas the ph of gastric juice is 8.0, which is highly alkaline.

- the optimum temperature for trypsin is about 98.6°f (37°c), which is the temperature of the intestine; whereas the temperature of gastric juice is 392 - 482°f (200°c - 250°c).
