The enzyme b-galactosidase converts the disaccharide lactose into?
A. allolactose B. Glucose C. allolactose and glucose D. allolactose, glucose, galactose E. sucrose and glucose
The enzyme beta -galactosidase convert lactose into allolactose, glucose and galactose. Hence, option d is correct.
The enzyme b-galactosidase converts the disaccharide lactose into? A. allolactose B. Glucose C. allolactose and glucose...
The natural inducer for the lac operon is A) lactose B) allolactose C) ?-galactosidase D galactose E good grde hydrolase
E. coli/brings lactose into its cell by using an enzyme called Lac Permease. Once the lactose is inside, another enzyme called B-galactosidase converts the lactose into galactose and glucose. 1. How is E. coll's way of dealing with lactose similar to how your celis do it? 2. How is it different?
2. Lactose is a disaccharide sugar composed of galactose and glucose that is found in milk. But how can we determine the order that the glucose and galactose are connected in this disaccharide? Use your knowledge of reactions from CHE 128 (e.g. alcohols, aldehydes and hemi-acetals) to propose an experiment (i.e. a series of reactions or experiments) that will answer this question. (this part counts as the BONUS question for quiz #5) OH HO OH OH HO OH HO HO...
1. Starch is a polymer made from the following monomer: a. a-galactose b. C-glucose c. B-glucose d. a-fructose 2. The type of bond that forms when a disaccharide is formed from two monosaccharides is called: a. a peptide bond b. a carbohydrate bond c. an ester bond d. a glycosidic bond 3. The products of hydrolysis of lactose are: a. glucose and galactose b. glucose and fructose c. galactose and ribose d. fructose and galactose 4. Which is the most...
What is the role of the protein encoded by the lacZ gene? What is the role of the protein encoded by the lacZ gene? The lacZ gene encodes an enzyme that converts lactose to allolactose, and the lacZ gene O O O O encodes an enzyme that converts lactose to glucose and galactose. The lacZ gene encodes an enzyme that permits lactose to enter the bacterial cell. The lacZ gene encodes an enzyme that converts lactose to glucose and galactose....

Describe the glycosidic bond of lactose. b. Draw the two monosaccharides that result when the glycosidic bond is hydrolyzed. 2. Draw the disaccharide maltose that forms when two a-D-glucose molecules condense forming an a( 14) glycosidic bond.
Enzymes are described as having specific substrates. For example, lactase enzyme breaks down the substrate lactose, a disaccharide, into glucose and galactose. Is lactase also able to break down starch, a polysaccharide made up of glucose?
Lactose intolerance occurs due to the enzyme deficiency of the enzyme lactase in the jejunum of the intestine. The lactase enzyme is found in specialized cells that break lactose down into glucose and galactose. The glucose is absorbed by the intestine and may be utilized by the cells through glycolysis, whilst the remainder of the glucose and galactose enter the glycolytic pathway. If there were to be a galactose intolerance, then it could be due to the deficiency/defects in the...
The inducer of the lactose operon in E. coli is CAP. cAMP. allolactose. glucose. galactos Codons refer to triplet base sequences in the mRNA. nontemplate strand of DNA. template strand of DNA. tRNA. rRNA.
Amylopectin is composed of A) glucose and fructose B) galactose and fructose C) glucose D) galactose E) glucose and lactose
