Lactase is a digestive enzyme that breaks lactose (a disaccharide) down to galactose and glucose (two monosaccharides). The following diagram illustrates the enzyme reaction cycle: 1. The component of the reaction labelled "A" in the diagram is A. Active Site B. Lactase C.
Lactose and lactase reaction diagram.
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.
1. Diagram (a simple sketch is fine) and describe the lactose/lactase reaction. 2. If there was a difference in reactivity between the two sugars, explain your results. 3. If there was a difference in reactivity between the unboiled and boiled enzymes, explain your results. 4. Describe what happened to the enzyme when it was boiled. 5.
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. Video of the Day
Lactose And Lactase Reaction Diagram To determine how the rate of hydrolysis of lactose by lactase is affected by temperature. The enzyme lactase present in the small intestine is essential for this reaction. Figure 1. A ball and stick model of lactose. Interpreting this diagram.
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 ...
1) Diagram and describe the lactose and lactase reaction? The lactose and lactase reaction consists of the substrate (lactase) approaching the active site of the enzyme. The lactase binds to the lactose forming an enzyme-substrate complex.The fit of the substrate and the enzyme has to be like a glove and a hand. Due to the energy, hydrogen bonds are broken down, and hydrolysis occurs (Lactose ...
This enzyme is responsible for a catabolic reaction that breaks down the dissaccharide lactose, a milk sugar. Lactose is a dissacharide consisting of a glucose molecule and a galactose molecule. Lactose intolerance is a condition in which individuals make an incorrect lactase molecule and have difficulty digesting milk sugar.
Aug 1, 2021 — An enzyme speeds up a chemical reaction which converts a substrate molecule or ... Was lactose digested when the enzyme lactase was present?
This type of milk has lactase enzyme added to it to hydrolyze the lactose before you drink it. diagram below shows the reactions involved in glucose detection.Lactose is a natural polymer of. • Lactose is made up of two simple sugars, but lactase is made up of amino acids chains folding into 3D structure.
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. Although lactose is similar to sucrose, lactase will break down only lactose
All chemical reactions are accompanied by a change in energy. ... A naturally occurring substrate of lactase is lactose (milk sugar) which is found in.12 pages

1. Diagram the Lactose and Lactase reaction. Label the substrate, the active site, the enzyme, the enzyme-substrate complex, and the products. 2. Sucrose, ordinary table sugar, is a disaccharide like lactose. Sucrose is composed of glucose and fructose. Sucrose and Lactose have the same chemical formula, C 12H 24O 11. Why then did the
Lactase is an enzyme. Like other enzymes, Lactase Enzyme is needed for a specific biochemical reaction in the body. The organic chemistry reaction that involves disaccharides breaks down disaccharide, a sugar in milk and milk merchandise. Some people's bodies don't build enough disaccharides so that they aren't able to digest milk well.

Label the diagram by dragging the labels to the appropriate targets. Note: not all targets will be used.
Answer (1 of 2): Lactose is a natural polymer of two sugars found in breast milk. Some folk have reactions or sensitivity to ingesting lactose containing foods. Lactase is an enzyme which splits the larger lactose sugar molecule into its constituents: glucose and galactose, at which point there's...
5.) Lactase is speeding up what type of chemical reaction-dehydration or hydrolysis? The chemical reaction is a hydrolysis reaction. It is a hydrolysis reaction because lactase catalyzes the reaction of lactose into glucose and galactose and a water molecule is added to the products.
Lactase nonpersistence, also called primary lactase deficiency, is the most common cause of low lactase levels. Congenital lactase deficiency. In this rare condition, the small intestine makes little or no lactase, starting at birth. Not all causes of lactose intolerance are genetic. The following can also lead to lactose intolerance:
In the lactose/lactase example the enzyme is lactase and the substrate is lactose. This means that lactose gets digested by lactase. The result of this reaction are two products: glucose and galactose. In the diagram below, label lactose, lactase, glucose and galactose.
Lactose must be digested by the enzyme lactase, before the products can be absorbed. ... The diagram shows the apparatus used to investigate the digestion of milk fat by an enzyme. The reaction mixture contained milk, sodium carbonate solution (an alkali) and the enzyme. In Experiment 1, bile was also added.

ABSTRACT. Globally, ∼70% of adults are deficient in intestinal lactase, the enzyme required for the digestion of lactose. In these individuals, the consumption of lactose-containing milk and dairy products can lead to the development of various gastrointestinal (GI) symptoms.
Lactose Intolerance Definition. Lactose intolerance is the inability to completely digest lactose, the sugar found in milk leading to symptoms such as bloating, cramps, gas, flatulence and possibly diarrhoea.. It is caused by the lack of an enzyme called lactase that is responsible for breaking down lactose found in milk and dairy products in the digestive system.
Lactase is able to only react with lactose to break lactose down into its monomers which are galactose and glucose (seen in the diagram). Is lactase used up during the chemical reaction? Enzymatic Activity of Lactase Enzymes are a class of protein molecules that act as biological catalysts.
