Please answer as many as possible 1. Substrate regulation of glycolysis and citric acid cycle (fructose-2,6-bisphosphate, fructose-1,6-bisphosphate, ADP, AMP-positive effectors of glycolysis enzymes; ATP, citrate, NADH, acetyl-CoA-negative effectors of glycolysis enzymes; ADP, AMP-positive effectors of citric acid cycle enzymes; ATP, NADH-negative effectors of citric acid cycle enzymes). 2. The role of the liver in the regulation of glucose concentration. 3. Hormonal regulation of glucose metabolism (the influence of epinephrine, glucagon, glucocorticoids, ACTH, STH, the central role of insulin in regulation of glucose metabolism). 4. Peculiarities of carbohydrate metabolism in the liver and muscles. 5. Peculiarities of carbohydrate metabolism in tumor cells.

In the clinical case scenario provided, match the defective enzyme in Column A with the consequence of this enzyme defect in Column B. IND OAD DH Autopsy results from individual X showed normal levels of glucose and pyruvate, very low levels of NAD+ and very high levels of NADH. Their blood oxygen levels were normal, although the cause of death was given to be a lack of oxygen. Option A B C D Defective enzyme Phosphofructokinase Pyruvate dehydrogenase Cytochrome oxidase Lactate dehydrogenase write your answer here Consequence of this enzyme defect Impaired ATP production Impaired NAD production Impaired respiration Impaired oxygen I L OORD ORD OND DORO G
True or False 1. Cytochrome-mediated oxidation reactions are facilitated by microsomal enzymes. 2. Drugs bound to plasma proteins are ready for therapeutic action 3. Sublingual tablets, when administered , do not undergo absorption. 4. Generally, drugs with high lipid solubility are better absorbed into the bloodstream. 5. Urinary excretion of weakly basic drugs is enhanced by increasing the pH of the urine. 6. Most drugs are absorbed through active transport mechanisms. 7. Lying on the left side increases gastric emptying rate.
It is required to recover active extracellular enzymes from a completed fermentation mediumthat also consists of proteins (<200,000 molecular weight cut-off (MWCO)) and bacterial cells (1-2μm). A cross-flow 0.35 μm microfiltration (MF) with retentate recycled back to the fermenter willbe used over a period of 5 hours during which time flux is assumed to decline linearly. After 5 hours, assuming 95% of the bacteria are retained and given the additionalinformation below, what is the concertation of bacteria remaining in the fermenter and what area,in m2 , of MF membrane is needed? Initial bacterial concentration = 1.2 gdcw /L (dcw = dry cell weight)Volume of medium at the beginning = 15 m3Volume of medium left in the fermenter after 5 hours filtering = 1 m3Initial (starting flux) = 6.5 x 10-5 m sec -1Final flux (after 5 hours of filtering) = 3.9 x 10-5 m sec -

Characterizing Glycolysis List the reactions of glycolysis that a. are energy consuming (under standard-stale conditions), b. are energy yielding (under standard-state conditions), c. consume ATP. d. yield ATP e. are strongly influenced by changes in concentration of substrate and product because of their molecularity. f. are at or near equilibrium in the erythrocyte (see Table 18.2).
Energetics of the Hexokinase Reaction The standard-state free energy change. Gfor the hexokinase reaction, is â€” 1 6.7 kJ/mol. Use the values in Table I to calculate the value of Gfor this reaction in the erythrocyte at 37Â°C.
