enzyme.

Postby Brett » Mon Feb 21, 2005 9:08 am

I know that temperature and ph increase enzyme's activity. How can I tell what the enzyme's activity would look like for an enzyme with ph of ex.8.5? Can I tell?
Help very much appreciated. thanks.

Brett, temperature does affect enzyme activity because it increases the random molecular movement of the substrate (more of a chance for a substrate to get into the active site of the enzyme). pH on the other hand does not affect how fast a reaction occurs (it will if the pH becomes too low or too high because the enzyme will become denatured). Enzymes try to help keep pH levels right in the middle so the enzyme itself doesn't become denatured. So a pH level of 8.5 would only have very small effects on the enzyme.

All enzymes have their OWN optimum. I mean we can not generalize a certain pH or temperature value for all enzymes.

I was not trying to do that... I just didn't make it that clear - sorry
