Peroxidase is an enzyme found in many organisms, from plant to humans. The function of peroxidase is to break down hydrogen peroxide, which is a toxin produced as a byproduct when oxygen is produced during respiration. Lactoperoxidase is found in human tissues, glands, and secretions, such as milk, tears, and saliva. It plays an important role in defense against pathogenic microorganisms in the intestinal tract of newborn infants and a protective role in sterility of secretions for the respiratory tract. For lactoperoxidase to function properly, thiocyanate is needed. A: Identify two examples of environmental factors that may impact lactoperoxidase activity. Describe how each of the environmental factors would affect the reaction rate of the enzyme.

B: Predict the effects of defects in the thiocyanate transport channels. Provide reasoning to justify your prediction.

like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.

actually, no it isn't. when i was in junior high school, it was a blast. considering that it was a pre international baccalaureate school.
