Question

compare the two pathways, which pathway shows the reaction that has taken place with the help of an enzyme? pathway 1, pathway 2, both reactions involved an enzyme, you cannot tell from these graphs.

Explanation:

Enzymes lower the activation energy ($E_a$) of a reaction. In the graphs, Pathway 2 has a lower $E_a$ (smaller peak height) compared to Pathway 1, indicating the reaction in Pathway 2 is catalyzed by an enzyme.

Answer:

Pathway 2
