1. Use the following graph to diagram the energetics of a
To describe:
The energetics of a chemical reaction with and without an enzyme. To position reactants and products at appropriate points and to indicate the stages in the reaction and the energy levels.
Introduction:
Enzymes are remarkable example of protein biocatalyst that facilitates metabolic reactions.
Explanation of Solution
Enzymes increase the rate of a chemical reaction without becoming part of the products or being consumed in the reaction. Because of the free energy inherent in molecules, a reaction could occur spontaneously at some point even without an enzyme but at a very slow rate.
Energitics of a chemical reaction with an enzyme:
Energitics of a chemical reaction without an enzyme:
Enzymes increase the rate of a chemical reaction without becoming part of the products or being consumed in the reaction.
