Question

1. How does changing the temperature affect the rate of enzyme activity?

2. Why might the enzyme activity decrease at very high temperatures?

3. How does changing the concentration of substrate affect the rate of decomposition of H2O2 by catalase?

4. How does changing the PH affect the rate of enzyme activity?

Answer 1

1). Enzymes are the proteins, which decrease the activation energy of reaction and catalyze the reaction process. But enzymes require appropriate temperature, pH, and other conditions for their functioning. Enzymes increase the rate of reaction at the appropriate temperature. The enzyme activity linearly increases with increase in temperature to a certain point. If the temperature is increased too higher or lower than the required temperature, the enzyme activity decreases.
