QUESTION 18 A metabolic pathway proceeds according to the scheme R-> S→> T→> U-> V -> W Which of the following statements is most likely correct for this pathway if a regulatory enzyme, enzyme X, catalyzes the first reaction in the pathway (R-> S)? OA. The last reaction product, W, is likely to be a negative allosteric modulator of enzyme X, leading to classic feedback inhibition OB. The product of the third reaction, Metabolite U, is likely to be a positive allosteric modulator, increasing the activity of enzyme X OC. The first reaction product S, is most likely the primary negative allosteric modulator of enzyme X, leading to classic feedback inhibition, Op. All five reactions will be catalyzed by the same enzyme X OE The last reaction product, W, is likely to be a positive allosteric modulator, increasing the activity of enzyme X Spoir
