There are two drugs P and Q that inhibit AK2's activity. You only have 3 nmoles of AK2 remaining from your purification. You decide to test these inhibitors in the lab. You generate the following dataset in three separate 10mL reactions that you follow spectrophotometrically. Vo Vo Vo (mM/sec) (mM/sec) (mM/sec) [Substrate] (mM) Control + Inh. P + Inh.
