- Blood lactate is a biochemical by-product that is produced during high-intensity exercise due to insufficient oxygen intake. Commercially available drinks advertised as oxygen sup- plements claim to increase exercise performance and decrease the postexercise recovery period by decreasing the accumulation and accelerating the removal of blood lactate. To test this claim, researchers conducted a controlled experiment to compare the concen- tration of blood lactate during exercise and during recovery between two participant groups, one that ingested oxygen-supplemented water and another that ingested regular water.

- You are studying the uptake of L-leucine by epithelial cells of the mouse intestine. Measurements of the rates of uptake of L-leucine and severalof its analogs, with and without Na+ in the assay buffer, yield the results given in the table below. What can you conclude about the properties and mechanism of the leucine transporter? Would you expect L-leucine uptake to be inhibited by ouabain?You are the lead scientist for a pharmaceutical company responsible for evaluating over 30,000 known compounds as potential drugs that inhibit a specific human enzyme that is often over-expressed in cancer cells. Your team has purified this phosphodiesterase and done initial assays to test for inhibition by all 30,000 compounds. You have asked your team to more fully test the two compounds that showed the strongest inhibition of the phosphodiesterase (both showed 50% inhibition of the phosphodiesterase at inhibitor concentrations of 1 g/ml. Below are the results for their enzyme assays of velocity (Velocity units are umoles of product formed per minute) of the reaction as a function of the substrate concentration.

- Which ONE of these statements is the most accurate definition of the mode of action of imatinib? Select one: A.It is a specific inhibitor of the BCR‐ABL1 fusion protein and blocks phosphatase activity by competing with adenosine triphosphate (ATP) binding B.It is a specific inhibitor of the BCR‐ABL1 fusion protein and blocks tyrosine kinase activity by competing with adenosine triphosphate (ATP) binding C.It is a specific inhibitor of the BCR‐ABL1 fusion protein and blocks tyrosine kinase activity by interaction with the enzyme site D.It is a specific inhibitor of the BCR‐ABL1 fusion protein and blocks phosphatase activity by interaction with the enzyme siteTwo GPCR mutations (Mutant A and Mutant B) were tested for activity. One was confirmed as being a constitutively activating, gain of function GPCR mutation and one was confirmed as being a loss of function GPCR mutation. Which is which? Explain your answer.Azathioprine is an immunosuppressant drug used in kidney transplants. In vivo, azathioprine is metabolized to the hypoxanthine analog 6- mercaptopurine, which is then converted into 6-mercaptopurine ribose monophosphate, the active form of the drug. 6- Mercaptopurine ribose monophosphate also inhibits de novo purine synthesis, reducing uric acid levels in the blood and urine. However, when administered to Lesch – Nyhan patients, there was no effect on uric acid levels. Explain why this is the case.
- You are studying a biochemical pathway and isolate Neurospora mutants I, II, and III.Mutant I can grow if you supplement the medium with Z.Mutant II can grow if you supplement the medium with X, Y, or Z.Mutant III can grow if you supplement the medium with X and Z, but not with Y. Draw a biochemical pathway that shows the correct order for compounds X, Y, and Z and for the enzymes that each mutant is defective for.For this exercise, an electron micrograph of secretory cells of the anterior pituitary is being used (Sandborn, E.B. (1970) Cells and Tissues by Light and Electron Microscopy, New York, New York: Academic Press, Inc.). The image originally measured 18.7 cm wide and 18.5 cm high with a magnification of 5200x.

Question 11 options: SDH oxidized succinate to fumarate, then fumarate reduced DCPIP. Succinate is blue in colour, which is eliminated by its oxidation to fumarate by SDH. SDH produced FADH2, then FADH2 reduced DCPIP. SDH generated DCPIP, then DCPIP oxidized succinate to fumarate.
