- The following reaction is catalyzed by this type of enzyme? Coo COO™ I HIC-H H-C-H COO™ succinate isomerase hydrolase O ligase transferase oxidoreductase succinate dehydrogenase FAD FADH2 H-C || C-H COO fumarateLactose intolerance is caused by reduced production of the enzyme lactase. A variety of digestive system problems, such as celiac disease and Crohn’s disease) can also lower the production of lactase. If an individual produces low levels of the enzyme lactase, explain why they might be able to tolerate eating dairy products that contain lower levels of lactose (e.g., hard cheeses, feta cheese, and cottage cheese), but will not be able to tolerate foods with high levels of lactose (e.g., milk).Many people who are lactose intolerant can eat yogurt, which is prepared from milk curdled by bacteria, without any digestive problems. Give a reason why this is possible. (Hint: Read the label on each of several yogurt containers. Do the ingredients make a difference?)
- Write the products of the oxidation and reduction of D-mannose. HO HO H- H- || C-H II H -ОН -ОН CH₂OH D-MannoseGalactose derived from lactose during milk consumption can be metabolized via the glycolytc pathway. Arrange the intermediates of galactose metabolism via glycolysis in order trom the first intermediate to the last intermediato. UDP-glucose Galactose UDPgalactose Galactose 1-phonphateWhat is the possible connection between the Urea cycle and other metabolic pathways? Can intermediates of the urea cycle can serve as precursors for amino acid, carbohydrate, fatty acid, and/or nucleotide metabolism (anabolism/catabolism). Give examples. . avoid copyrighting and plagiarism.
- Fructose is a labeled on its anomeric carbon with 14C. This labeled fructose is added to muscle cells under anaerobic glycolytic conditions, and the secreted lactate is collected. Which carbon in the secreted lactate (shown below) contains the 14C label? دیده OH Carbon 2 Carbon 1 Carbon 3 No carbon contains the label.The rate-limiting enzyme of fatty acid synthesis pathway is Select one: O Acetyl CoA carboxylase O 3-Ketoacyl-AC synthase O Malonyl CoA-ACP transacylase O Acetyl CoA-ACP acetyltransacylaseMany people suffer from lactose intolerance. Outline how food products containing milk may be made ‘lactose free’, and thus helping to avoid triggering the condition.
- Using albinism and phenylketonuria as examples, explain what is meant by inborn errors of metabolism.Explain what happens to milk proteins during the formation of yogurt. (HInt: yogurt is made by fermentation of milk by bacteria, typically Lactobacillus bulgaricus and Streptococcus thermophillus. The bacteria convert milk sugar to lactic acid.)The FMO3 enzyme has an important physiological function in people. State the normal substrate of FMO3 in people and describe a genetic polymorphism that can reduce the activity of this enzyme. Describe the consequence to people with the reduced FMO3 activity. Give at least one reference from the primary literature (i.e. a scientific journal) to support your answer.
