Question

Option that describes an enzyme:

A specialized protein that helps chemical reactions to occur (without being change by the reactions)

Answer 1

Your description is accurate. An enzyme is indeed a specialized protein that acts as a catalyst in biochemical reactions. It facilitates chemical reactions by lowering the activation energy required for the reaction to proceed, allowing the reaction to occur more efficiently and at a faster rate. Importantly, enzymes themselves are not consumed or permanently altered in the process, which means they can be used repeatedly in multiple reaction cycles.
