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

A.
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.
B.
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.
C.
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).

Respuesta :

The enzyme trypsin get deactivated when introduced in the gastric juice of the stomach because A. 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.

What is trypsin?

Trypsin is a peptidase enzyme that is responsible for protein hydrolysis to form smaller peptides and amino acids. This enzyme is produced in the pancreas and is secreted in the duodenum to be an important part of digestion. The enzyme is secreted in its inactive form and after it reaches the duodenum it is activated by enteropeptidases.

Being active, it will carry out its function by hydrolyzing peptide bonds, making them smaller, thus making it possible for them to be absorbed by the intestine membrane.

Therefore, we can confirm tha the enzyme trypsin get deactivated when introduced in the gastric juice of the stomach because A. 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.
