9) You have isolated a bacterium from some spoiled food in your refrigerator. After isolating a pure culture of this bacterium, you inoculate it into a tube containing a growth. Which tube best depicts the expected distribution of bactcria within the tube, if the organism is a microacrophile? broth that will suppot its A BC D E 10) From the data contained in the figure, which molecule is best described as a substrate?

9) Test tube labelled "D" represents the microaerophiles because it is found on the upper part of the test tube (but not on the top). Microaerophiles require only a low amount of oxygen so they are confined to upper part. Test tube "A" represents obligate aerobes, test tube "B" represents obligate anaerobes, test tube "C" represents facultative bacteria, and test tube "E" represents aerotolerant bacteria.
10) A. PEP. PEP and ADP are the substrate which converted to products: pyruvic acid and ATP. Mg2+ acts as cofactor for the enzyme.
