(a)[2]
Outline how an enzyme may be 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 free solution.
(c)[4]
Papain is a protease enzyme. Its activity at different temperatures, when immobilised onto an inert support, was compared with its activity in solution. The results are shown in Fig. 2.1. Using Fig. 2.1, describe and explain the differences in the activity of immobilised papain and papain in solution.
