Which of the following correctly identifies the effect that the presence of an uncompetitive inhibitor has on a Lineweaver - plot?

W) K\({}{\rm m}\)[K-M] and V\({}{\rm max}\)[V max] are raised, and the ratio K\({}{\rm m}\)/V\({}{\rm max}\)[K-M over V max] increases X) K\({}{\rm m}\) and V\({}{\rm max}\) are raised, and the ratio K\({}{\rm m}\)/V\({}{\rm max}\) is unchanged Y) K\({}{\rm m}\) and V\({}{\rm max}\) are lowered, and the ratio K\({}{\rm m}\)/V\({}{\rm max}\) is unchanged Z) K\({}{\rm m}\) and V\({}{\rm max}\) are lowered, and the ratio K\({}{\rm m}\)/V\({}{\rm max}\) decreases
Y) K\({}{\rm M}\) AND V\({}{\rm MAX}\) ARE LOWERED, RATIO K\({}{\rm M}\)/V\({}{\rm MAX}\) IS UNCHANGED
