Question

In an experiment to study the effect of amylase on starch, samples of substrate and enzyme solutions are taken. The volumes of substrate and enzyme solutions in each sample are the same. The temperature at which the experiment is performed is also constant. The buffer solutions used for the experiment have pH 3, pH 5, pH 7, pH9, and pH 11. What can be best predicted about the result ?

Answer 1

It catalyzes the breakdown of starch. When amylase reacts with starch, it cuts off the disaccharide maltose (two glucose molecules linked together). ... As amylase breaks down starch, less and less starch will be present and the color of the solution (if iodine is added) will become lighter and lighter.
