Through our observations we have concluded that an increase in enzyme concentration will speed up the breakdown process further. The higher the temperature, the slower the rate of enzyme activity, the lower the temperature the faster the rate of enzyme activity. This is due to the fact that enzymes are living organisms, and organisms tend to function best at intermediate levels. This is true when observing different pH levels and their effect on enzyme activity. The lower the level of pH, the faster the rate of enzyme activity; the higher the level of pH, the slower the rate of enzyme activity.
