PART III: EFFECTS OF pH ON ENZYME ACTIVITY

Submitted by ekim on Thu, 10/11/2007 - 3:06pm.

Saskia Guerrier, Eurie Kim

Hypothesis
The lower the pH, the faster the "hydrogen peroxide + Catalase B" reaction; the higher the pH, the slower the "hydrogen peroxide + Catalase B" reaction.

Observations
pH2.0
trial 1: 70 secs*outlier
trial 2: 30 secs
trial 3: 30 secs
trial 4: 30 secs
AVG: 30 secs

ph7.4
trial 1: 24 secs
trial 2: 23 secs
trial 3: 19 secs
AVG: 22 secs

ph10.4
trial 1: 21 secs
trial 2: 19 secs
trial 3: 21 secs
AVG: 20.3 secs

At Wil's request, we did pH7.4 & pH10.4 over again.
pH7.4
trial 1: 15 secs
trial 2: 14 secs
trial 3: 14 secs
AVG: 14.3 secs

pH10.4
trial 1: 23 secs
trial 2: 20 secs
trial 3: 20 secs
AVG: 21 secs
