product

denaturation

if an enzyme is exposed to extreme pH or temperature, it's active site changes shape, and no longer fits to its substrate

optimum temperature

the highest point of the graph, the temperature of the most enzyme activity. past the optimum temperature, the enzyme begins to denature
