Question

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
