The structure of a substrate P strongly resembles substrate Q. In an experiment, By mistake P was used instead of Q as a substrate for the enzyme, Q-ase. The results obtained were identical to the results that would have been obtained using substrate Q. Why did substrate P work in place of substrate Q?
A) P and Q are coenzymes
B) P and Q are holoenzymes
C) P and Q have similar binding properties
D) P and Q have different binding properties

Respuesta :

The structure of the substrate P and Q is mostly similar. This strong structural similarity would mean that the binding properties of these two different substrates might also be similar. The production of similar results by using substrate P instead of the substrate Q ensures this similarity. The substrate P binded with the enzyme similar to the substrate q and resulted in the same products.

Hence, the correct answer is 'Option C- P and Q have similar binding properties'.
