Q2. (a) Starch can be used to produce fructose for slimming foods. The flow chart shows the process. (i) Isomerase is used to change glucose into fructose. Which enzyme could be used to change the starch into glucose? Draw a ring round one answer. carbohydrase isomerase protease (1) (ii) What is the advantage of using fructose, instead of glucose, in slimming foods? Tick () one box. Fructose is not as sweet as glucose so can be used in smaller amounts. Fructose is sweeter than glucose so can be used in larger amounts. Fructose is sweeter than glucose so can be used in smaller amounts. (1) (b) Enzymes are used in industry. These are some of the properties of industrial enzymes: enzymes work at low temperatures •
