Some bacterial cells can grow on either ethanol (CH 3 CH 2 OH) or acetate (CH 3

Question:

Some bacterial cells can grow on either ethanol (CH3CH2OH) or acetate (CH3COO) as their only carbon source. Dr. Schwips measured the rate at which the two compounds traverse the bacterial plasma membrane but, due to excessive inhalation of one of the compounds (which one?), failed to label his data accurately.


A. Plot the data from the table below.image


B. Determine from your graph whether the data describing compound A correspond to the uptake of ethanol or acetate. Explain your answers.

C. If you wanted to determine the rate of transport for compounds A and B at different concentrations of substrate, what equations would you use for each?
