Question

A double-reciprocal plot of 1/V0 versus 1/[S] for an enzyme in the presence of increasing concentrations of an uncompetitive inhibitor will have lines corresponding to the different inhibitor concentrations that are BEST described by which statement?a) The lines will intersect at the x-axis to the left of the y-axis.b) The lines will cross the y-axis and will be parallel to each other.c) The lines will intersect to the left of the y-axis but above the x-axis.d) The lines will intersect below the x-axis, to the right of the y-axis.e) The lines will be parallel to each other but will not cross the y-axis.

Answer 1

Answer:

The answer is b) The lines will cross the y-axis and will be parallel to each other.

Explanation:

In the attached image you can see the double reciprocal graph where non-competitive inhibition is described. This non-competitive inhibition is characterized in that the inhibitor can only bind to the enzyme substrate complex.
