Hint 1] |H Resources Answer Y The graph shows three plots of velocity (vy) versus substrate concentration ([S]) . Determine which curve represents an enzyme's reaction velocity without any inhibitor present, which curve represents the velocity in the presence of a noncompetitive inhibitor, and which curve represents the velocity in the presence of a competitive inhibitor. Vimax| Macmillan Learning \\ i no inhibitor Vimax / competitive inhibitor Yo , noncompetitive inhibitor [S] (M) Select all of the true statements. L] When substrate is present in excess, the maximum reaction rate is unchanged in the presence of a competitive inhibitor. Q A higher substrate concentration is associated with a faster reaction rate if the enzyme is not saturated. [_] A competitive inhibitor decreases the maximum rate at which a reaction can proceed
