What does pepsin work at 37 degrees C?

Pepsin is an enzyme that functions optimally in the acidic environment of the stomach, where it is active at around 37 degrees Celsius, the normal human body temperature. At this temperature, pepsin effectively breaks down proteins into smaller peptides, facilitating digestion. Its activity is significantly enhanced in the low pH environment of gastric juice, which is crucial for its catalytic function. Overall, 37 degrees Celsius provides ideal conditions for pepsin's enzymatic action.
