In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and returns to the liver. In the liver, lactate is converted back into glucose by gluconeogenesis. For each given enzyme, identify whether it is involved in the glycolysis pathyway, gluconeogenesis pathway, both pathways, or neither pathway. a. glyceraldehyde 3-phosphate dehydrogenaseb. glycolysis. c. gluconeogenesis. d. both. e. neither 2. glucose-6-phosphatasea. glycolysis. b. gluconeogenesis. c. both. d. neither 3. alcohol dehydrogenasea. glycolysis. b. gluconeogenesis. c. both. d. neither 4. phosphoenolpyruvate carboxykinasea. glycolysis. b. gluconeogenesis. c. both 5. phosphofructokinase-1 a. glycolysis. b. gluconeogenesis. c. both. d. neither 6. phosphoglycerate mutase a. glycolysis gluconeogenesis. b. both. c. neither 7. hexokinase a. glycolysis. b. gluconeogenesis. c. both neither 8. pyruvate dehydrogenase a. glycolysis. b. gluconeogenesis.

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i.e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
