Question

The pepsin that helps a deer break down the food in its stomach will begin to break down the deer's stomach after it dies. True or False?

A) True
B) False
C) Depends on specific conditions
D) Not mentioned in the passage

Answer 1

False. Pepsin activity stops after the deer dies and the pH of the stomach becomes less acidic.

Step-by-step explanation:

False

Pepsin is an enzyme that is secreted by the chief cells in the stomach and helps digest proteins. It works best in the highly acidic environment of the stomach, with an optimum pH of about 1.5. However, after a deer dies, the activity of pepsin will stop due to the cessation of secretion and the pH of its stomach will eventually become less acidic.
