Question #5299f

Answer 1

The human body functions at a pH of `7` also.

Explanation:

The human body and many of its enzymes (with exception of the stomach and other organs) function at a pH of `7.00`. In fact, an increase to `7.10` can be enough to kill someone. Therefore, the lactase enzyme is perfect for the human body since they both operate at the pH of `7.00`. In terms of the structure and function of proteins, they both are similar, as they both should be appropriately suited to neutral pH conditions.

I hope that helps!
