Calculate the concentration of BSA in each sample and say if the standard curve is adequate for each of these samples? Why or why not? If not, what would you do to fix this? Show your calculations.Question 1: When the CAC is run in reverse by microorganisms that use it to fix carbon, the citrate synthase reaction is different and is catalyzed by an enzyme called ATP-citrate lyase. Write the reaction catalyzed by ATP-citrate lyase, then briefly (in one sentence) explain why the use of different chemistry (different from the ‘normal’ direction) makes sense here.Question 56 You (a healthy individual) are swimming underwater when you can no longer resist the urge to breathe.
