Use Figure 3.2 to explain why the amount of chemical potential energy of a compound is less than the amount of chemical potential energy of the atoms that comprise the compound.

• The compound has more stable bonds.

• The atoms have higher individual energy.

• Energy is released during bond formation.

• The compound has a higher energy state.

Which of the following best describes the relationship among the concepts: free energy, endergonic reactions, exergonic reactions, and entropy?

• Free energy is the energy available to do work, endergonic reactions require energy input, exergonic reactions release energy, and entropy is a measure of disorder.

• Free energy is the energy released in exergonic reactions, endergonic reactions increase entropy, and entropy is a measure of energy.

• Endergonic reactions release free energy, exergonic reactions require energy input, and entropy decreases in all reactions.

• Free energy is unrelated to endergonic and exergonic reactions, and entropy is a measure of energy efficiency.

What is a metabolic pathway, and why are metabolic pathways advantageous to a cell?

• A series of chemical reactions occurring within a cell, providing energy and building blocks for the cell.

• A single chemical reaction that occurs in isolation within a cell.

• A process that occurs outside the cell and has no impact on cellular function.

• A random sequence of reactions that do not contribute to cellular efficiency.

Which law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another?

• First law of thermodynamics

• Second law of thermodynamics

• Third law of thermodynamics

• Zeroth law of thermodynamics

Some people claim that life’s high degree of organization defies the laws of thermodynamics. How is the organization of life actually consistent with the principles of thermodynamics?

• Life decreases entropy locally while increasing it globally.

• Life violates the second law of thermodynamics.

• Life creates energy from nothing.

• Life does not follow any thermodynamic laws.

What type of reaction is shown in each graph? Choose the correct type of reaction from the options below.

• Exothermic reaction

• Endothermic reaction

• Combustion reaction

• Neutralization reaction

What type of reaction would need energy to be supplied? Which would have energy released?

• Endothermic reactions need energy to be supplied; exothermic reactions release energy.

• Exothermic reactions need energy to be supplied; endothermic reactions release energy.

• Both endothermic and exothermic reactions need energy to be supplied.

• Neither endothermic nor exothermic reactions release energy.

Which of the following best describes a spontaneous reaction?

• A reaction that occurs without external intervention

• A reaction that requires continuous energy input

• A reaction that never reaches equilibrium

• A reaction that decreases entropy

Why is the recycling of electron carriers and ATP important for the cell?

• It helps in maintaining energy balance.

• It prevents the accumulation of waste products.

• It ensures continuous supply of energy.

• It supports cell division.
