[2025-10-01T20:19:45.339260] [PI reasoning] **Classifying enzymes**

I see that there's a straightforward question about enzyme classification. It revolves around how enzymes are categorized based on the nature of the reaction they catalyze, specifically regarding the substrate and reaction type. So, option A seems like the best choice. I'll say that action on the substrate aligns well with this classification. Next, I should prepare some citations and look for at least one reference to support my response. Let's do a quick search!
