Filtration is a method for removing living cells, vegetative cells, and bacterial spores from a dilute aqueous solution or air. Which of the following statements can be used to describe this process? Choose all that apply. May cause breaks or pyrimidine dimers in DNA Cannot reliably remove viruses Utilizes filters with very small pores ( 0.22 microns) There is no thermal damage associated with this process Is considered a bacteriostatic Can be used with liquids and gases 3 points You are working in a lab to create mutants in the energy metabolism pathways of prokaryotic organisms. Your mutant however seems to grow poorly in medium containing standard amounts of glucose as carbon source. You take a log-phase culture of cells of the mutant, and the parental wild-type bacteria as a control, and you make extracts of the cells. You then perform some metabolite determinations to see if you can determine where the problem arises. Based on the metabolite levels in the table below, you hypothesize that the defect in . the mutant's metabolism is at the Kreb's Cycle the glycolysis step the proton pump mechanism the electron transport chain
