When the terminal phosphate is cleaved from the ADP 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 10–2 M, what are the concentrations of the predominant forms of phosphate that exist at pH 7.4?
Suppose Gina climbs a high mountain where the oxygen partial pressure in the air decreases to 70 torr. Assume that the pH of her tissues and lungs is 7.4 and the oxygen concentration in her tissues is 20 torr. The P50 of hemoglobin is 26 torr. The degree of cooperativity of hemoglobin, n, is 2.8. Estimate the percentage of the oxygen-carrying capacity that she utilizes. Calculate your answer to one decimal place. capacity: %
Explain why a dispersion of silver nanoparticles coated with an amine functionalised polymer would be more stable at low pH than high pH.
The amino acid serine has two pKa values, one for its carbonyl group (pKa = 2.21) and one for its NH3+ group (pKa = 9.15).These pKa values help to determine the isoelectric pH (also known as the isoelectric point, pI). The pI is the pH at which the substance has a charge of zero. It affects how the amino acid moves in gels of different pH values during electrophoresis.
A 0.800 ml aqueous solution of NADH shows an absorbance at 340 nm of A = 0.333. Express (in nanomole (nm) units) how much NADH is contained in the sample. (e340 = 6290 mol • L −1 • cm
Suppose Gina climbs a high mountain where the oxygen partial pressure in the air decreases to 80 torr. Assume that the pH of her tissues and lungs is 7.4 and the oxygen concentration in her tissues is 20 torr. The Pso of hemoglobin is 26 torr. The degree of cooperativity of hemoglobin, n, is 2.8.

There are many organic acids and bases in our cells, and their presence modifies the pH of the fluids inside them. It is useful to be able to assess the pH of solutions of acids and bases and to make inferences from measured values of the pH. A solution of equal concentrations of lactic acid and sodium lactate was found to have pH= 3.08. (a) What are the values of pKa and Ka of lactic acid? (b) What would the pH be if the acid had twice the concentration of the salt?
