Understand the role of enzymes: Enzymes are biological catalysts that speed up chemical reactions in the body without being consumed in the process.
Recognize that enzymes do not provide energy themselves; instead, they lower the activation energy required for a reaction to occur, making the process faster.
Note that enzymes are not permanently altered during reactions. They can be reused multiple times for the same reaction type.
Clarify that enzymes do not store genetic information. This is the role of nucleic acids like DNA and RNA.
Conclude that the correct description of enzymes in metabolism is that they act as catalysts to speed up metabolic reactions without being consumed.
