Effect of temperature and pH on enzymes
Biology · Secondary 3 · Medium · Effect of temperature and pH on enzymes
The rate of an enzyme-controlled reaction was measured at different pH values.
The rate was highest at pH 8 and much lower at pH 3 and pH 11.
Which statement explains these results?
The rate was highest at pH 8 and much lower at pH 3 and pH 11.
Which statement explains these results?
- The enzyme has an optimum pH around 8; extreme pH changes its active site.
- The substrate is only present at pH 8.
- The enzyme concentration is highest at pH 3 and pH 11.
- The enzyme works best when it is denatured at pH 8.
