- Question 1: In acute lymphoblastic leukemia, the cancerous white blood cells typically lack the enzyme asparagine synthetase. Why is the administration of asparaginase an effective therapy for this type of cancer?QUESTION 10 Select a property that does not belong to allosteric enzymes. They conform to hyperbolic Michaelis-Menten kinetics They may have binding sites for regulatory molecules that are separate from active sites They tend to have a signmoidal curve of rate versus [S] They undergo conformation changes as a result of modulator binding.Question 1 The creation of milk products such as cheeses and yogurts is dependent on the conversion by various anaerobic bacteria, including several Lactobacillus species, of lactose to glucose and galactose, ultimately producing lactic acid. These conversions are dependent on both permease and β-galactosidase as part of the lac operon. After selection for rapid fermentation for the production of yogurt, one Lactobacillus subspecies lost its ability to regulate lac operon expression. Would you consider it likely that in this subspecies the lac operon is “on” or “off”? What genetic events would likely contribute to the loss of regulation as described above? Question 2 Contrast the role of the repressor in an inducible system and in a repressible system.

- QUESTION 4 Goldberger's direct research contributions leading to identification and replacement of the P-P factor (pellagra preventive factor), the missing dietary element associated with pellagra, included all of the following, except? He studied a pellagra analog disease in laboratory dogs by feeding them a corn-rich diet. He supplemented a corn-rich diet with brewer's yeast in dogs and then in humans to support that brewer's yeast provided the p-p factor. He oversaw the distribution of tens of thousands of pounds of brewer's yeast to flooded areas of the south to successfully treat populations suffering from pellagra. He identified niacin (abundant in brewer's yeast) as the elusive P-P factor. He established a standard dosage and therapy for niacin.QUESTION 10 A) In glycolysis, the glucose which has 6 carbon molecules is eventually broken down into 2 molecules of 3 carbon compounds as pyruvate. Regardless of all the enzymes involved, describe the key points that change the 6 carbon compound into two molecules of 3 carbon compound. B) As glycolysis splits glucose into two pyruvate molecules, the link reaction occurs twice per molecule of glucose. Briefly explain the process after pyruvate transported from the cytosol into the mitochondrial matrix.Question 174 Why are false-negative results usually more common than false-positive results in biochemical and metabolic assays that detect the product of enzymatic reactions? O Positive results require the product being assayed for to be formed in adequate quantities to be observed and this is unlikely to occur spontaneously. O Cultures that do not grow well during the incubation for some reason can test negative due to low product formation even when they do have the enzyme being assayed for All of these O Most assays require a reagent to react with a product to produce a color change, and failure to react, perhaps due to bad reagents, will be interpreted as negative.
