Question no 1. - thus graph explain that the optimum pH for proper functioning of enzyme (urease) is 6-7 (enzyme show maximum catalytic activity) if we are increasing the pH from 7 to 8 or 9 the activity of urease is decreased. As urease is a globular protein to it works at an optimum ph. If we are changing the pH . It can lead to denaturation.
At 3 pH enzyme was not active.
The activity of urease is decreased when we are increasing the pH from 8 to 9
Add Answer to:
Urease is an enzyme which 'catalyses the breakdown of urea to ammonia and carbon dioxide. An...
