The term that describes enzymes involved in biochemical reactions is "catalysts." Catalysts are substances that accelerate chemical reactions without being consumed in the process. Enzymes, which are biological catalysts, lower the activation energy required for reactions, allowing them to occur more quickly and efficiently. This catalytic activity is crucial in many biological processes, including metabolism and cellular signaling.

In contrast, colloids refer to a mixture where one substance is dispersed evenly throughout another, but they do not function in the same way as enzymes. Cathodes are electrodes through which current enters a polarized electrical device, unrelated to enzymatic activity. Constants are fixed values in mathematical equations or laws, but they do not pertain to biochemical reactions or the role of enzymes. Thus, "catalysts" is the term that accurately captures the role of enzymes in facilitating biochemical reactions.
