PDF Dusty Carroll Lesson Plan 4: Getting to know Lactase ... Lactase can act as a catalyst for several different biological reactions. The lactase enzyme is the only human enzyme that can cleave a β-glycosidic linkage like that found in lactose. The specific reaction that is the focus of this lesson is the breakdown of lactose into the two monosaccharides, galactose and glucose as seen in the reaction ... Measuring Lactase Enzymatic Activity in the Teaching Lab Lactase catalyzes the hydrolysis of the glycosidic bond in the disaccharide lactose, releasing galactose and glucose ( Figure 2) 5. These monosaccharides are then used primarily for the generation of adenosine triphosphate (ATP) via the citric acid cycle and oxidative phosphorylation 6.

DOCX Biology I Lab: Enzyme Function Lactase is an enzyme that breaks lactose down into galactose and glucose. Lactase can be purchased in pill form by people who are lactose intolerant. These people lack the enzyme, lactase, and cannot break down the sugar lactose into its component parts. Lactase is specific to lactose sugar and will not break down other disaccharides.

A Description of Lactose and Lactase Reaction | livestrong Lactose is milk sugar; you consume it any time you drink milk or eat dairy products. To absorb its components and use them for energy, you digest it with lactase, an enzyme produced by your digestive tract. Lactase reacts with lactose, splitting it into two smaller sugar molecules that you can absorb. Advertisement Video of the Day Lactase Enzyme Lab - Adobe Spark In a lactose and lactase reaction, lactose, the substrate, fits into lactase's (the enzyme) active site. This reaction is a hydrolysis reaction, which means it requires water to produce products. When the substrate lactose binds into lactase's active site, it forms the enzyme substrate complex. Team Conference Two - Lactose Lab 2. Write the chemical formula for cellular respiration. C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP. 3. Diagram and describe the lactose and lactase reaction. In a lactose reaction, the lactose separates into glucose and galactose. In a lactase reaction, lactase breaks the bonds in lactose to produce galactose and glucose. 4.
