Given: A 10,000L bioreactor may have 100 trillion cells. Let’s assume that this cell solution has the same density as water.
(answer A, B, and C)
A. What cell density is this (per kg)?
B. What is the ratio of cell density in your body compared to that in a bioreactor?
C. What is limiting cell densities in a bioreactor that your body has managed to overcome?
The investigators reported that the sphingosine kinase enzyme attached to the DEAE column when Tris was used as a buffer, but not when a phosphate buffer at the same pH was used. Explain the difference in behavior. The structure of the conjugate base of the Tris buffer is shown below. Hint: consider what charges all these molecules have at pH 7.4
The enzyme urease increases the rate of urea hydrolysis at pH 8.0 and 20 °C by a factor of 10^14. Suppose that a given quantity of urease can completely hydrolyze a given quantity of urea in 10 minutes at pH 8.0 and 20 °C. How long would it take for this amount of urea to be hydrolyzed in the absence of urease at the same temperature and pH in sterile conditions?

- Reverse osmosis uses extreme pressure to force water through many layers of selectively permeable membranes. This traps the salt and other dissolved solutes on one side of the membrane, while pure water builds up on the other side. explain why this process is called "reverse osmosis" and describe at least one positive or negative impact of using this technology to desalinate water.arrow_forwardThe catalytic mechanism of an enzyme found in the mitochondrial matrix (pH = 7.8) depends on an active site Lys residue (pKa = 9.5) that acts as a general acid. Mutation of a neighboring residue alters the microenvironment of the Lys side chain so that its pKa shifts from 9.5 to 7.2. Would the mutation cause the reaction rate to increase or decrease? Explain your answer.arrow_forwardDNA, which is negatively charged, can adsorb onto the surface of citrate-capped Au nanoparticles.
