Biology Graphs: Enzymes and Rates of Reactions

An enzyme is a biological catalyst that speeds up a reaction rate. It will not cause a reaction to occur that would not normally happen. In biological systems temperature and pH affect an enzyme's ability to function. At too high a temperature enzymes denature and break down, therefore losing their functionality.

General Questions


At what temperature do both enzymes have an equal rate of reaction?
1. 





At what temperature does GlenKeppie have a maximum activity rate?
2. 





What conclusion can you draw to explain the effect of temperature on this graph?
3. 





Extension:
Why might a high fever be dangerous to a human? What might be happening?
4.
