Concept explainers
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.

- A reducing chemical reaction. reduces the compound to a simpler form adds an electron to the substrate removes a hydrogen atom from the substrate is a catabolic reactionarrow_forwardIn the following graph: A represents the product. B represents the energy of activation when enzymes are present. C is the free energy difference between A and D. C is the energy of activation without enzymes. E is the difference in free energy between the reactant and the products.arrow_forwardWhich of the following comparisons or contrasts between endergonic and exergonic reactions is false? Endergonic reactions have a positive ?G and exergonic reactions have a negative ?G Endergonic reactions consume energy and exergonic reactions release energy Both endergonic and exergonic reactions require a small amount of energy to overcome an activation barrier Endergonic reactions take place slowly and exergonic reactions take place quickly.arrow_forward
