How do pH and enzymes interact in a lab setting?

[Jbreezy]

Homework Statement

Hi just a quick question. I was doing a lab report and this enzyme is supposed to work between the pH of 6.7 and 7. So I had solution of .0125 N and I said OK just subtract this from 7.0 and say that is the new Ph. So for instance 7.0 -0.125 = 6.98
I said OK this is within range so the enzyme should work. I just made this up.

If not worse.

See if these two pages: short introduction to buffers and buffer calculation examples won't help.
