Students’ prior knowledge and understanding can be used as a base from which to introduce the greater depth and breadth required at A Level. The enzymes topic also provides an opportunity for students to develop some An immobilized enzyme is an enzyme, with restricted mobility, attached to an inert, insoluble material—such as calcium alginate (produced by reacting a mixture of sodium alginate solution and enzyme solution with calcium chloride). This can provide increased resistance to changes in conditions such as pH or temperature. It also lets enzymes be held in place throughout the reaction, foll…
