Human xanthine oxidase catalyzes the oxidation of hypoxanthine to xanthine and can further catalyze the oxidation of xanthine to uric acid. For the treatment of hyperuricemia and gout, several medications are used to inhibit the activity of xanthine oxidase and reduce the production of uric acid. You are a biochemist and just discovered a chemical that can inhibit the activity of the human xanthine oxidase. When analyzing its mode of inhibition, you found that the enzyme inhibitor complex requires 450 J.mol’ to dissociate and that it displays kinetics somehow similar to noncompetitive inhibition. You sent your inhibitor to the ministry of health for approval as a medication for gout. Based on the data provided, are they going to authorize it as a medication or not? Explain?

Outline within 400 words the ethical concerns and consideration issues you i identify with tissue engineering.

EXPERT ANSWER Tissue engineering is capable of enhancing or replacing physiological and biochemical functions that may be damaged by injury or sickness. It is a part of regenerative medicine and it is rapidly evolving. It applies both the principles of engineering and life sciences that could restore or improve tissue functions. The ethical concerns can …

Problem 6: Three friends, Alex, Luke and Emma, had a bike race. At an instant t=0, Alex was 10 meters ahead of Emma and Luke was 18 meters ahead of her. Alex was biking with a constant speed 6 m/s. Luke had a speed 10 m/s. He was slowing down with acceleration 0.8 m/s2. Emma was trying to catch up with the boys. At an instant t=0, her speed was 5 m/s and her acceleration was 1.2 m/s2. Plot the graphs of motion of three friends and find at what time Emma will catch up Alex and Luke and at what distance from the initial position.
