You are to convert the 5 mM fumaric acid in a waste stream into malate using fumarase immobilized on nonporous spherical particles. The enzyme has a turnover number of 23/sec, and a Km of 1.55 mM. The immobilized enzyme particles are 1 mm in diameter, and they contain 99.4 x 10-4 mg enzyme/cm2 of support. The mass transfer coefficient is 2 x 10-4 cm/sec. The molecular weight of fumarase is 48,000.a) What is the fumaric acid concentration on the surface of the particles?b) What is the effectiveness factor for the immobilized enzyme?c) What should the reaction rate be to treat 1 liters of the waste stream per day?d) What surface area is required to yield the required reaction rate?e) How many particles would be required?
Richard does not know it, but he has an aneurysm at the base of his left middle cerebral artery. One of Richard favorite activities is to take a hot sauna bath and then jump into cold water.
The bacteria are allowed to grow overnight and are streaked on a plate using the technique that produces isolated colonies that are clones of the original. Samples of these colonies are then grown in four different media: nutrient broth plus ampicill..
A double-stranded piece of DNA, 100 base pairs in size, is exposed to a high pH environment. This causes all non-valent interactions to be disrupted.
Sidney Brenner discussed that the code was non overlapping because he considered that coding restrictions would occur if it were overlapping.
Lysosomes are single membrane-enclosed, 0.2-0.5 m diameter spherical vesicles inside the cytosol of eukaryotic cells. Estimate the concentration of H+ inside lysosomes.
Explain an experiment to test this hypothesis. Be explicit about the methods you will use, the setting, the time that the experiment will last, and the variables you will measure.
Mitochondria are now day descendants of endosymbiotic bacteria. How many different RNA polymerases would you expect to find in Drosophila mitochondria?
Hutchinson-Gilford progeria is an exceedingly rare human genetic disorder in which there is very early senility, and death, usually of coronary artery disease, at an average age of approximately 13. Patients, who look very old even as children, do no..
