A research group discovers a new version of happyase, which they call happyase*, that catalyzes the chemical reaction HAPPY ⇌ SAD. The researchers begin to characterize the enzyme. (a) In the first experiment, with [Et] at 4 nM, they find that the Vmax is 1.6 μM s−1. Based on this experiment, what is the kcat for happyase*? (Include appropriate units.)

(Include appropriate units.) (c) Further research shows that the purified happyase used in the first two experiments was actually contaminated with a reversible inhibitor called ANGER. When ANGER is carefully removed from the happyase preparation and the two experiments repeated, the measured Vmax in (a) is increased to 4.8 μM s−1, and the measured Km in (b) is now 15 μM. For the inhibitor ANGER, calculate the values of α and α′. . (d) Based on the information given…
Scientists can determine the age of ancient objects by a method called radiocarbondating. The bombardment of the upper atmosphere by cosmic rays converts bitrogen toa radioactive isotope of carbon, C-14, with a half-life of about 5730 years. Vegetationabsorbs carbon dioxide through the atmosphere and animal life assimilates C-14 throughfood chains. When a plant or animal dies it stops replacing its carbon and the amount ofC-14 begins to decrease through radioactive decay. Therefore, the level of radioactivitymust also exponentially decay. A parchment fragment was discovered that had about74% as much C-14 radioactivity as does plant material on the earth today. Estimate theage of the parchment.
Scientists can determine the age of ancient objects by the method of radiocarbon dating. The bombardment of the upper atmosphere by cosmic rays converts nitrogen to a radioactive isotope of carbon, 14C, with a half-life of about 5,730 years. Vegetation absorbs carbon dioxide through the atmosphere, and animal life assimilates 14C through food chains. When a plant or animal dies, it stops replacing its carbon, and the amount of 14C present begins to decrease through radioactive decay. Therefore, the level of radioactivity must also decay exponentially. a) Dinosaur fossils are too old to be reliably dated using carbon-14. Suppose we had a 67 million year old dinosaur fossil. What percent of the living dinosaur's 14C would be remaining today? (Round your answer to five decimal places.) b) Suppose the minimum detectable amount is 0.7%. What is the maximum age (in years) of a fossil that we could date using 14C? (Round your answer to the nearest year.)

Dinosaur fossils are often dated by using an element other than carbon, like potassium-40, that has a longer half-life (in this case, approximately 1.25 billion years). Suppose the minimum detectable mass is 0.4% and a dinosaur is dated with 40K to be 67 million years old. Is such a dating possible? What is the maximum age (in millions of years) of a fossil that could be dated using 40K? (Round your answer to one decimal place.) (Can you…
suppose there was a release of 0.572 mole of particle A and 0.792 mole of particle B and both particles are accelerated to 5.73 MeV. What is the energy in terms of kJ/mole for both particle A and B?

A teacher developed a new chemical - NONDISTRACTUS, which allows students to focus in the classroom more and not be distracted by random events. For NONDISTRACTUS to be effective there must be a minimum concentration in the student's body of 2.00 x10-3 mol / L. If the concentration falls below this level, the students are faced with a 10 min nonproductive period where they cannot focus on anything. NONDISTRACTUS was found to undergo a very rapid first-order decay with a half-life (t½) in the bodies of students of 23 min. Based on this information:a) What is the rate law constant, k?b) If the student starts off with an initial concentration of 2.25 x 10-2 mol / L dose, how long will it be until the concentration is above the minimum 2.00 x 10-3 mol / L? Will it ensure that they are not distracted for the entire test?
