Which of the following best explains the fact that patient specimens are typically assayed at saturating substrate concentrations so that v is at Vmax?
A) To ensure that only the concentration of enzyme in the specimen affects the measured rate B) To fit the data onto the standard curve generated by "y = mx + b" C) To more closely mimic the enzymatic reaction as it occurs in vivo where enzymes generally only function at Vmax D) To prevent inactive enzyme molecules from being mistakenly counted as substrate.
