How to use radioactive Fe-59 (a beta emitter with half life of 44.5 days) to determine the extent to which rabbits are able to convert a particular iron compound in their diet into blood hemoglobin, which contains iron atoms?

how does high pressure O2 treat CO poisoning?

Could you please help answer this question?

I was trying to set this problem where the units cancel out. You are given ampicillin, with a recommended dose of 35 mg/kg , to a child with a mass of 21 kg. If stock on hand is 250 mg/ capsule, how many capsules should be given. How should I set this conversion problem up and it's also asking to express the number of capsules as an integer

Name four important amines that are producing during cadaver degeneration. Explain each.

You've discovered a new organism that contains a mutant form of Hemoglobin (red line on right) and are testing its properties in a lab setting at a neutral pH. You've generated the binding data below comparing it to the wildtype (non-mutant; blue line on left) form. Oxygen binding of a new hemoglobin mutant 1.00 - 0.75- Hemoglobin 0.50 - Wildtype Mutant 0.25- 0.00 - 25 50 75 100 pO2 (torr) 1. How does this mutation seem to impact cooperativity? Hint. Look at the slope of the line. [ Select ] 2. Which variant, the mutant or wildtype, has a higher affinity for oxygen? [ Select ] 3. Which variant is a more effective delivery system to the the muscles (~20 torr)? Select ] Fraction of Hb bounw with Oxygen

You have discovered a new hemoglobin variant you are calling Hb-21. You have noticed the following from your studies of Hb-21: - The binding constant of Hb-21 is the same at pH 7.1 and 7.4.- The binding constant curves generated by Hb-21 and O2 are sigmoidal.- The Hill coefficient for Hb-21 is 3.-The binding constant for Hb-21 with O2 in the presence of 5mM 2,3-bisphosphglycerate is about 6-times lower instead of the 8-times lower that is observed under these conditions for the wild type enzyme. Use this information to answer questions: Based on this information which of these features of hemoglobin would you conclude are altered in Hb-21 as compared to the wild type hemoglobin? ____ the cooperativity.____ the amount of T versus R state in the tissues. ____ the Bohr effect. What is the major issue for an individual with the Hb-21 variant? Explain exactly what aspect of hemoglobin’s function is altered.

The image shows a whole body bone scan using MDP (mono-diphosphonate) labelled with technetium-99m. • Patient is injected with 600 MBq of Tc-99 MDP • Technetium-99m is a pure gamma emitter, with physical half life of 6 hours. a) Use the data to explain why technetium 99-m is a suitable radionuclide (AC 3.1)

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. The researchers determined the kcat of the enzyme to be 452 s-1. In a separate experiment with [E;) at 1.5 nM and [HAPPY) at 38 µM, the researchers find that Vo is equal to 320 nM s-1. What is the measured Km of happyase* for its substrate HAPPY? Make sure to include units in the answer.

What does an A280 of 0.000 indicate? What does this reading indicate in the context of your column chromatography? Are there still proteins adhering to the column? Do you know anything about the proteins which are still adhering to the column?
