List two differences you would expect to see in the composition of lipids in the E. coli membrane when the cells are incubated at 25 ∘C compared to incubation at 37 ∘C. Match the items in the left column to the appropriate blanks in the sentence on the right.

1 shorter fatty acids2 longer fatty acids3 trans4 cis1. The membranes of cells grown at 25 °C would have with a greater number of double bonds compared to the membranes of cells grown at 37 °C.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
