Question

drag the labels onto the diagram to identify the steps in a reaction both with and without enzymes. diagram includes axes: energy (horizontal), progress of reaction (vertical); labels: reactants, without enzyme, with enzyme, stable product; numbered boxes 1–4; and activation energy required section

Explanation:

• In a reaction diagram, the starting point (lowest energy, initial substances) is reactants, so 4 is Stable product (end of reaction, low energy, stable), 1 is Reactants (start).
• Enzymes lower activation energy, so the pathway with lower activation energy (dashed or the one with less energy rise) is "With enzyme" (2), and the higher activation energy pathway is "Without enzyme" (3).

Answer:

1: Reactants
2: With enzyme
3: Without enzyme
4: Stable product
