(b) In the non-competitive inhibition of enzymes, the inhibitor (cyanide) has no structural similarity with the substrate (cytochrome-c) and binds to the enzyme at a point other than its active site which leads to change in globular structure of enzyme. Hence, even if the substrate is able to bind with the enzyme, catalysis will not take place. |
