In the graph to the right it shows the activation energy needed in a reaction. Assuming that both Lines A and B are of the same reaction which line likely had an enzyme present? How do you know?

Curve B represents the presence of an enzyme since it requires lower activation energy.
Enzymes are biologiacal catlysts. All the biologicals reactions are faster because of enzymes. The catalysts drastically accelerate any reaction in which they are present by lowering the activation energy required for the reaction.
So if we look at the given graph we can see that the curve B represents lower activation energy for the same reaction. Therefore curve B must represent the reaction in which an enzyme is present.
