Investigation on the effect of ph

This lab is only investigating the effect of temperature on enzyme activity, not the effect of ph on enzyme activity, so nothing should be added to the liver that would increase or decrease the ph | time | if some pieces of liver are kept in their specific temperatures longer than others, the height of the reaction could be greatly affected.
