A reseаrcher clаims thаt sоme bacteria cоntain factоrs that influence the function of a particular enzyme but other bacteria do not. To test the claim experimentally, the researcher will grow two different bacterial strains in separate liquid cultures and isolate the contents of the cells in each culture. The researcher will add different combinations of cellular contents, substrate, and enzyme to test tubes containing a buffer solution adjusted to the optimal pH of the enzyme and then measure the rate of product formation. The design of the researcher’s experiment is presented in Table 1. Table 1. An experiment for investigating the influence of bacterial factors on enzyme function Test Tube Source of Cellular Contents Cellular Contents Added Substrate Added Enzyme Added 1 Strain 1 No Yes Yes 2 Strain 1 Yes No Yes 3 Strain 1 Yes Yes No 4 Strain 1 Yes Yes Yes 5 Strain 2 No Yes Yes 6 Strain 2 Yes No Yes 7 Strain 2 Yes Yes No 8 Strain 2 Yes Yes Yes Which of the following statements best justifies the inclusion of test tubes 3 and 7 in the experiment?
