Question

1. identify the parts of the graph below using the following terms: products, reactants, activation energy with no enzyme, activation energy with an enzyme.

a.
b.
c.
d.

Explanation:

• Reactants: Reactants are the starting substances in a chemical reaction. In an energy - level diagram, they are represented at the beginning of the reaction (left side). So, \(A\) is the reactants.
• Activation Energy with an Enzyme (\(E_a\) with enzyme): Enzymes lower the activation energy. The dashed line represents the reaction pathway with an enzyme. The peak of the dashed - line curve (\(B\)) is the activation energy with an enzyme.
• Activation Energy without an Enzyme (\(E_a\) without enzyme): The solid - line curve represents the reaction without an enzyme. The peak of the solid - line curve (\(C\)) is the activation energy without an enzyme.
• Products: Products are the substances formed at the end of a chemical reaction (right side of the energy - level diagram). So, \(D\) is the products.

Answer:

A. Reactants, B. Activation Energy with an Enzyme, C. Activation Energy without an Enzyme, D. Products.
