(a)[2]
Outline the method by which an enzyme is immobilised in alginate.
(b)[2]
State two advantages, apart from stability, of using an immobilised enzyme in an industrial process rather than the same enzyme in solution.
(c)[4]
Papain is a protease enzyme. Its activity at different temperatures was compared in the immobilised state and in solution. The findings are shown in Fig. 2.1. Using Fig. 2.1, describe and explain the differences in activity between immobilised papain and papain in solution.
(d)[4]
Using Fig. 2.1, describe and explain how the activity of immobilised papain differs from that of papain in solution.
