Final answer:
The experiment involves testing the effect of lactase on milk with lactose and observing the enzymatic action on lactose and sucrose, including the impact of high temperatures on the enzyme's effectiveness.
Step-by-step explanation:
The activity described requires the preparation of several solutions to observe the enzymatic action of lactase on lactose. Lactase is an enzyme that catalyzes the hydrolysis of lactose, a sugar in milk, into glucose and galactose. This is an important process for individuals with lactose intolerance, a condition where they cannot produce sufficient amounts of lactase.
In this experiment, regular and lactose-free milk are tested for glucose presence before and after the addition of lactase tablets. Furthermore, sucrose, which is hydrolyzed by sucrase into glucose and fructose, is also used in this experiment to compare the enzymatic activity. Lastly, the experiment involves heating a lactase solution to boiling to observe how this affects enzyme activity.
In examples provided, it is highlighted that sugars like maltose and lactose can be broken down through hydrolysis, either by enzymatic activity or by means of a dilute acid catalyst at high temperatures. The solutions made with sugar and water where sucrose is the solute dissolved in water, the solvent, illustrate the concept of a solution in chemistry.
