Which statement identifies the graph with the enzyme? Graph B, because the enzyme binds to the reactant, lowering the activation energy needed for the reaction to occur

Graph A, because the enzyme releases energy from the reactant, changing the amount of product formed

Graph A, because the enzyme combines with the reactant molecule, producing a different end product

Graph B, because the enzyme absorbs the energy from the reactant, increasing the speed of the reaction

Answer 1

The correct statement that identifies the graph with the enzyme is:

**Graph B, because the enzyme binds to the reactant, lowering the activation energy needed for the reaction to occur.**

This is consistent with the role of enzymes, which facilitate chemical reactions by lowering the activation energy, allowing the reaction to proceed more quickly without changing the overall energy of the reactants and products.
