Ammonia must be eliminated from wastewater before it can be reused, recycled, or discharged. Describe the three major steps that are used to convert harmful ammonia into a harmless derivative. Your answer must be specific and include any appropriate chemical formulas or names of chemical or biological reagents. Mention, when appropriate, the toxicity of any of the components or how their production can get in the way of efficiently eliminating ammonia from wastewater.

When the terminal phosphate is cleaved from the adenosine triphosphate molecule, the products are adenosine diphosphate and inorganic phosphate,  ATP + H2O  ––>  ADP  +  Pi, where Pi stands for the various forms of phosphate that exist at the pH of the particular solution.  If the total concentration of Pi  is 2.5 x 10–2M, what are the concentrations of the predominant forms of phosphate that exist at pH 7.4?

Paragraph 5: Discuss Fractional Distillation of petroleum oil to give the chemical feedstock to make synthetic polymers for commercial use of products in our daily lives and discuss your personal thoughts on incresing US drilling in the Gulf of Mexico or in the Artic. Think about it, every time you go to the grocery store and get a plastic bag which immediately gets discarded. Include your thoughts on mandatory recycling in the US especially for schools, government buildings, etc.

What are the criteria for essential elements in relation to biological systems. Explain the concept of essentiality.

Alanine (HA) is a diprotic amino acid with Kal = 4.53 x 10-3 and K₁2 = 1.36 x 10-10. Determine the pH of each of the solutions. A 0.241 M alanine hydrochloride (H₂A+CI-) solution. pH = A 0.241 M alanine (HA) solution. pH = A 0.241 M sodium alaninate (Na+ A¯) solution. pH =

Distinguish between mixed-acid fermentation and butanediol fermentation and describe the test(s) that can be used to detect each. Briefly describe the reactions and changes that take place during the decarboxylation of amino acids in the decarboxylase medium. Explain the experiment that you would perform in order to determine whether the organism that you were instructed instructed to identify is positive or negative for gelatin hydrolysis. How do microorganisms such as bacteria eliminate harmful reactive oxygen species? Nitrate reduction to nitrite is indicated by the formation of a pink to red color after addition of nitrate test reagent. However, if a culture does not produce a colour change several possibilities exist. Explain.

You ask the individual if they are taking any non-prescription drugs.  They tell you they recently started taking a coenzyme Q10 supplement based on a recommendation from a friend.  The structure of coenzyme Q10 is shown below.  Looking at the structure of the molecule, which one of the 4 major classes of macromolecules (carbohydrate, lipid, proteins or nucleotides) does it most closely resemble?  Be sure to include specific chemical characteristics that support this decision.

Include the balanced chemical equation for the reaction being studied or conducted (reactants to products). indicate actual chemical structures that pertain to the experiment and indicate conditions as well as solvents over and under the reaction arrow.

Triglycerides are composed of three fatty acids bonded to a glycerol backbone. Explore the structures and properties of triglycerides. The carbon-carbon double bonds of triglycerides will react with hydrogen gas in the presence of a metal catalyst such as Pt. This process will convert the unsaturated triglycerides to saturated triglycerides. What quantity in moles of H, gas would be required to convert this triglyceride to a fully saturated triglyceride?
