Fig. 4-2. Variation of the rate with the substrate concentration for type A substrate 

 inhibition (Eq. 4-2). Curve 1: /?= x, y = x (uninhibited); curve 2:« = x,^ = y = 5; 

 curve 3: a = 10, ^ = y = 5; curve 4: a = 3, ;8 = y = 5; curve 5: a=l, ^ = y = 5. 



Fig. 4-3. Variation of the rate with the substrate concentration for type A substrate 

 inhibition (Eq. 4-2) using the pS scale. The vahxes for the curves are the same as 



in Fig. 4-2.
