A student carried out an investigation to compare the mass of glucose produced from the breakdown of each substrate. The same mass of amylose and amylopectin was used and all other variables were kept constant. The results of the investigation are shown in the graph. Analyse the data to explain the rate of breakdown of amylopectin and amylose by
