Final answer:
The three variables that are analyzed for influence on starch activity are temperature, pH, and substrate concentration. Temperature and pH are environmental factors that can alter enzyme activity, while substrate concentration directly affects how frequently enzyme-substrate interactions occur.
Step-by-step explanation:
The three variables analyzed for influence on starch activity are temperature, pH, and substrate concentration.
Temperature is a critical factor that affects enzymes. An increase in temperature accelerates the reaction rate up to an optimum point, after which the enzyme is denatured and the reaction rate declines. The optimum temperature is where the enzyme activity is at its maximum.
pH also plays a significant role in enzyme activity. Each enzyme has an optimal pH at which it performs best. Deviations from this pH can result in reduc
Lastly, the substrate concentration affects the rate of enzyme-catalyzed reactions. An increase in substrate concentration generally leads to a corresponding increase in enzyme activity, up to a point where the enzyme becomes saturated, and any further increase in substrate concentration does not enhance the reaction rate.
