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?

At what temperature does GlenKeppie have a maximum activity rate?

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

Why might a high fever be dangerous to a human? What might be happening?
