Enzymes — practice question
A scientist studied how alterations in pH affected the activity of two different protease enzymes. Each enzyme was put into a hole in the centre of a protein jelly layer in a Petri dish. The investigation used a range of pH values. After 60 minutes, the area of jelly broken down by enzyme L or enzyme M was measured for each pH value tested.
