Passage VII
Enzymes are large protein molecules that increase the rate of chemical reactions in living systems. The substrate is the substance that interacts with the enzyme in a reaction. The acceleration factor is the factor by which the enzyme increases the rate of a reaction. Figures 1–3 show the effects that changes in temperature, pH, and substrate concentration have on the rate of reaction of a substrate when Enzymes A and B are present. Figure 4 shows the effects that changes in the concentrations of Enzymes A and B have on the rates of reaction in substrate solutions of the same concentration.
39. A scientist claims that for the conditions used to obtain the data for Figure 4, the acceleration factor of Enzyme B at a given concentration will always be greater than that of Enzyme A at the same concentration. Do the data support his conclusion?
Your Answer is
Correct Answer is A
Explanation
Look at figure 4, the acceleration factor of B is generally lower than that of A, so the statement in the question stem is wrong
