NEET Zoology Biomolecules Questions Solved


Go through the figures and select the correct option:

(a)     I - In non-competitive type of enzymatic inhibition the V max decreases and Km           remain unchanged

II - In competitive type of enzymatic inhibition the Vmax decreases and Km remain           unchanged

(b)     II - In non-competitive type of enzymatic inhibition the Vmax decreases and Km           remain unchanged

          I - In competitive type of enzymatic inhibition the Vmax remain same and Km is           changed

(c)     I - In non-competitive type of enzymatic inhibition the Vmax increases and Km           remain unchanged

          II - In competitive type of enzymatic inhibition the Vmax changes and Km      decreases

(d)     I - In non-competitive type of enzymatic inhibition the Vmax increases and Km           remain unchanged

          II - In competitive type of enzymatic inhibition the Vmax increases and Km    increases

The adjoining graph shows change in concentration of substrate on enzyme activity (velocity of the reaction).

Fig- II : competitive enzymatic inhibition- Vmax decreases and Km remains unchanged

Fig- I : non-competitive enzymatic inhibition- Vmax remains unchanged and Km is changed
