Which statement best describes the relationship between proteins and enzymes?

The relationship between proteins and enzymes is fundamentally important in biochemistry. Proteins are large, complex molecules made up of long chains of amino acids. Enzymes are a specific type of protein that act as biological catalysts, speeding up chemical reactions in the body without being consumed in the process.

Since enzymes are composed of amino acids, they fall under the broader category of proteins. In fact, each enzyme's unique structure, which is determined by its specific sequence of amino acids, allows it to perform its particular function effectively. Thus, the correct statement underscores the fact that enzymes are indeed a main component of proteins, as they are a specialized form of protein that facilitates various biochemical processes necessary for life.
