Understanding Enzyme Active Sites

Enzymes are biological catalysts that facilitate chemical reactions in living organisms. They are largely composed of proteins, and their structure is crucial for their function. The basic structure of an enzyme includes an active site that binds substrates, leading to the formation of products. Understanding enzyme structure is essential in fields such as biochemistry and pharmacology.

One critical aspect of enzyme function is the role of amino acids in the active site. These amino acids can be polar or non-polar, and their properties significantly affect substrate binding and reaction rates. Additionally, some enzymes require cofactors or coenzymes for optimal activity.

Based on this information, identify the statement which correctly lists a feature of an enzyme's active site.
