<h3><u>Answer;</u></h3>
C) P and Q have similar binding properties
<h3><u>Explanation;</u></h3>
- <u><em>Enzymes are biological catalysts that speeds up chemical reactions. Substrates are substances that are acted on by an enzyme to form a product.</em></u>
- <u><em>An enzyme catalyzed reaction occurs when the substrate binds to the active site of an enzyme to form and enzyme-substrate complex. </em></u>
- <em><u>Substrate P and Q are structurally similar which means they are in a position of binding and fitting in the active site of an enzyme. The strong structural similarity means that the binding properties of these two different substrates may be similar. </u></em>
- <em><u>Formation of similar products or results when acted upon by an enzyme mean they are similar in terms of their binding properties, and thus the production of similar product.</u></em>
