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 and 2 show the effects that changes in temperature, and pH have on the rate of reaction of a substrate when Enzymes A and B are present.

Answer 1

Based on the information provided:

Question 1: According to Figure 2, Enzyme A has the fastest rate of reaction at a pH closest to:

• The correct response is likely 8. Enzymes often have an optimal pH range, and if the graph indicates that Enzyme A performs best around this point, it's reasonable to select 8.

Question 2: Based on the data in Figure 2, at which of the following pHs, if any, do Enzymes A and B have the same acceleration factor?

• The correct response is likely At none of the pHs shown in the diagram. This suggests that throughout the measured pH range, the enzymes maintain different levels of activity, never matching.

Please confirm these interpretations with the actual figures in question for accuracy.
