- The following question focuses on how the parameters regulating enzyme function might change, and how these might appear graphically on a Michaelis-Menten plot and a Lineweaver-Burke plot. Carbonic anhydrase is an enzyme that will convert CO2 and water into HCO3. CO2 + H20 > H+ + HCO3 There are many different isoforms of this enzyme. (see for instance http://en.wikipedia.org/wiki/Carbonic_anhydrase . Assume that one variant has a Km of 10 µM and a different variant has a Km of 100 µM. Draw on the same graph a typical Michaelis-Menton plot showing the alteration in the rate of carbonic anhydrase as the CO2 level is varied for the two different variants of enzyme, assuming the concentration of the enzyme (10 mM) in the test tube is kept constant. Assume that you have equal amounts of the two different variants of carbonic anhydrase in a number of test tubes and that the Vmax for both enzymes are the same. Be sure to label the axes.

Enter Your Answer:Tyrosinase enzyme activity is assayed by monitoring the oxidation of 3, 4-dihydroxyphenylalanine (dopa) to the red-colored dopachrome. Calculate the tyrosinase activity (U/mL) by using the experimental data given belowCorticosteroids (a type of hormone), and Nonsteroidal Anti-inflammatory Drugs (NSAIDs) are non-narcotic pain relievers. Both medications are prescribed to reduce inflammation in the body. NSAIDs such as aspirin, acetaminophen, and ibuprofen are able to reduce pain, fever, and inflammation by blocking the action of the cyclooxygenase enzyme (COX) that catalyzes the conversion of arachidonic acid into prostaglandins. Common corticosteroids include prednisone, cortisone, and methylprednisolone. Choose one of these three corticosteroids. Do some internet research on the corticosteroid that you choose and then explain how the drug works to reduce inflammation.

Note: There may be more than 1 correct response. Ribose 5-phosphate ribose phosphate pyrophosphokinase (PRPP synthetase) glutamine-PRPP amidotransferase adenylosuccinate synthetase AMP -> PRPP 5-Phosphoribosylamine I adenylosuccinate lyase 9 steps Adenylosuccinate AMP IMP <-- ADP <- AMP <-- GMP <-- IMP IMP dehydrogenase <- GMP. XMP ADP ATP XMP-glutamine amidotransferase GMP يا Increased levels of ADP inhibit the production of PRPP. Increased levels of GMP inhibit the production of XMP. Increased ADP activates PRPP synthase to increase PRPP levels. Increased IMP activates glutamine-PRPP amidotransferase to further increase IMP levels.PKU Worksheet Read the following paragraph about a genetic disorder identified as an inborn error of metabolism. Illustrate your understanding of metabolic pathways and mutations by responding to the guiding questions. Please also use this link ( https://rarediseases.org/rare-diseases/phenylketonuria/ ) for more information. Phenylketonuria (PKU) is an inherited disorder that is identified as an inborn error of metabolism. It is easily detectable during the first days of life through newborn screening tests. A drop of the infant’s blood can determine the presence of the enzyme that is responsible for processing the essential amino acid phenylalanine. With normal enzyme activity, phenylalanine is converted to another amino acid (tyrosine), which is then utilized by the body to produce melanin (pigmentation in hair, skin, eyes), thyroid and other hormones. However, when the phenylalanine hydroxylase enzyme is absent or deficient, phenylalanine abnormally accumulates in the blood. A…
