Verified answer

I just wanted to let you know that i'm in medical technology school, we learned all about this stuff and I have NO IDEA what the answer is. I'm looking it up in my books though.

... all i know is that changing the pH usually denatures or inhibits the enzyme. Maybe it somehow adds more substrate with the solution. Maybe the pH of the liver was more acidic to begin with, thus, adding the basic solution brought it closer to its optimum pH.

I really don't have any hard facts, sorry i'm not much help.
