"because the reaction is to slow to make an effect, if a enzyme is added then it can hydrolyse lactose but it can take more than 6 years without the addition of an enzyme" Is bull**** the real answer is because the active site of the two substances are different and so the sucrase becasue Lactose has a different shape/structure which does not fit/bind to active site of enzyme/sucrase.
What else can I help you with?
What are the products of hydrolysis of maltose?
When a molecule of lactose is hydrolyzed the monomers that had linked together to form lactose will be pulled away from each other through the addition of lactose. Lactose is made from GLUCOSE AND GALACTOSE, henceforth these two monomers will emerge through the hydrolysis of lactose. Hope this helps...
What is the difference between a fecal and non-fecal coliform?
Fecal coliforms have the ability to ferment lactose at 44C +/- 0.05C while regular coliforms ferment lactose at 35C-37C
What kind of sugar is used by organisms?
Organisms use all types of sugars, ex. we eat lactose (milk) fructose (fruit) and sucrose (white sugar used in cooking) . Organisms break the sugars down into their parts, ex lactose= galactose+glucose
Would you be able to distiguish maltose from lactose in a unknown sample from doing barfoed's test?
Both maltose aswell as lactose are disaccharides, where maltose is made up of two glucose units, whereas lactose is made up of 1 unit of glucose and 1 unit of galactose. Barfoed's test answers only for mono and disaccharides. Presence of red precipitate would indicate a positive result for monosaccharides. Thus doing Barfoed's test does not distinguish between maltose and galactose since both are disaccharides.
What is macconkey agar made out of?
Macconkey agar consists of agar, lactose, peptone, neutral red dye, crystal violet dye & bile salts. Bile salts inhibit growth of Gram positive bacteria & allow growth of Gram negative bacteria only. It differentiates lactose fermentating Gram negative bacteria from non lactose fermentating Gram negative bacteria.
Which sugar when hydrolyse would yield a molecule of glucose and galactose?
lactose
If lactase breaks down lactose and galactose then the enzyme sucrase breaks down?
The enzyme sucrase breaks down sucrose. Glucose and fructose are the products of this chemical reaction.
Which enzyme cannot generate glucose is it Lactase or Amylase or Maltase or Sucrase All of them?
Lactase cannot generate glucose. It is an enzyme that breaks down lactose into glucose and galactose. Amylase, maltase, and sucrase are enzymes involved in the breakdown of carbohydrates into glucose.
What happen to lactose that is not digested in the small intestine?
A: Lactose, or milk sugar, is digested by the enzyme lactase. Lactase is produced in the small intestine. It catalyses (speeds up) the digestion of lactose into two smaller sugars, glucose and galactose.
Name the three disaccharides and the enzymes that break them down into monosaccharides?
sucrose - common table sugar = glucose + fructoselactose - major sugar in milk = glucose + galactosemaltose - product of starch digestion = glucose + glucose
What enzymes metabolizes CHO's?
Enzymes such as amylase, sucrase, and lactase are responsible for metabolizing carbohydrates (CHO's) in the body. Amylase breaks down starch into sugar, sucrase breaks down sucrose into glucose and fructose, and lactase breaks down lactose into glucose and galactose.
What measured as an indicator of sucrase activity and why this is an indicator of sucrase activity?
Sucrase activity is measured by quantifying the amount of glucose produced by the breakdown of sucrose by sucrase enzyme. Glucose is an indicator of sucrase activity because sucrase specifically breaks down sucrose into glucose and fructose. Therefore, the more glucose produced, the higher the sucrase activity.
What enzymes are needed to breakdown disaccharides?
The enzymes needed to break down disaccharides are sucrase (for sucrose), lactase (for lactose), and maltase (for maltose). These enzymes are required to hydrolyze the glycosidic bond holding the two sugar units together in the disaccharide.
What is measured as an indicator of sucrase activityand why this is an indicator of sucrase?
Sucrase activity is often measured by quantifying the amount of glucose released from sucrose as it is broken down by sucrase enzyme. This is a reliable indicator of sucrase activity because sucrase specifically targets sucrose and converts it into glucose and fructose, providing a measurable output for enzyme function.
What hydrolyse starch?
amylase enzyme
What are some common enzymes?
Lactase is a common enzyme that breaks down lactose. Other common enzymes are diastase with aids in breaking down vegetable starch, sucrase which digests sugars, and protease which breaks down proteins
What do the Lysosomes do in an animal cell?
hydrolyse substances
