Enzyme Action Flashcards
1
Q
Enzymes effect to temperature
A
As the temperature increases, so does the rate of reaction. But very high temperatures denature enzymes. The graph shows the typical change in an enzyme’s activity with increasing temperature. The enzyme activity gradually increases with temperature up to around 37ºC, or body temperature.

Q
Enzymes effect to Ph
A
Changes in pH also alter an enzyme’s shape. Different enzymes work best at different pH values. The optimum pH for an enzyme depends on where it normally works. For example, intestinal enzymes have an optimum pH of about 7.5. Enzymes in the stomach have an optimum pH of about 2.
