People who are lactose intolerant lack the lactase enzyme. They often experience digestive problems when they eat dairy products. Do the results of Demetri's experiment support this scenario? Explain your response.
sugar and water
sugar and lactase enzyme in water
sugar and heated lactase enzyme in water
Test Tube 4 - Sugar (Sucrose): Demetri fills the fourth test tube one-quarter full of sugar. He then adds water to the test tube until it is three-quarters full and stirs until the sugar dissolves. Demetri then inserts the test strip for 30 seconds and records its color.
Test Tube 5 - Sugar (Sucrose) and Lactase Enzyme: Demetri fills the fifth test tube one-quarter full of sugar. He then adds the lactase-and-water solution until the test tube is three-quarters full. He thoroughly mixes the solution and inserts the test strip for 30 seconds. Demetri then records the color of the test strip.
Test Tube 6 - Sugar (Sucrose) and Heated Lactase Enzyme: Demetri fills the sixth test tube one-quarter full of sugar. He then adds the heated lactase-and-water solution until the test tube is three-quarters full. He thoroughly mixes the solution and inserts the test strip for 30 seconds. Demetri then records the color of the test strip.
