Question

The Effect of Various Factors on the Rate of an Enzyme Reaction. These experiments will use the enzyme catalase, which is found in potatoes. Catalase acts on the substrate, H₂O₂ (hydrogen peroxide), to produce H₂O and O₂. The O₂ is released as bubbles. Therefore, the more bubbles you see, the greater the reaction.

Base your responses on the following data table:

The effect of temperature on the rate of enzyme reactions

Tube	Pre-Treatment Temp °C	Treatment Temp °C	Prediction - no bubbles + some bubbling ++ strong bubbling +++ very strong bubbling	Observations - no bubbles + some bubbling ++ strong bubbling +++ very strong bubbling
C1	100	100	+++	-
C2	25	25	++	+++
C3	0	4	+	++

What do you conclude about the effect of temperature on enzyme activity? Don’t just say that it has an effect, say how it affects it.
Based on your conclusion, do you think you might digest ice cream at a slower or faster rate than a hot soup?
