To determine: Whether either reaction of the given reactions (reaction 1 or reaction 2) is capable of performing work.
Introduction: Equilibrium constant represents the relation between reactants and products in a reaction at equilibrium. The concentrations of reactants and products are constant at equilibrium. Under conditions of a biochemical reaction, free energy (G) is defined as the amount of energy available to perform work.

- EVOLUTION LINK Some have argued that evolution is impossible because the second law of thermodynamics states that entropy always increases; therefore natural processes cannot give rise to greater complexity. In what ways is this statement a misunderstanding of the laws of thermodynamics?arrow_forwardFigure 6.8 Look at each of the processes shown, and decide if it is endergonic or exergonic. In each case, does enthalpy increase or decrease, and does entropy increase or decrease?arrow_forwardWhat statements concerning free energy change are true or false? a. Free energy change is a measure of the rate of a reaction. b. Free energy change is a measure of the maximum amount of work available from a reaction. c. Free energy change is a constant for a reaction under any conditions. d. Free energy is related to the equilibrium constant for a specific reaction. e. Free energy change is equal to zero at equilibriumarrow_forward
- Calculate the standard free energy change (ΔG°′) for the following reaction: ½ O2 + FADH2 → H2O + FADarrow_forwardRefer to Model 10.1 and answer the question that follows What is free energy? What is its symbol?arrow_forwardWhen the temperature rises from 100°C to 145°C, the rate of a certain reaction increases by 3.7. 1) Calculate the reaction's activation energy in J/mol 2) Determine the ratio between the rates at 100°C and 45°C?arrow_forward
- For this reaction: 6CO2 + 6H2O → C6H12O6 + 6O2, the products have 2760 kJ/mole more free energy than the reactants. So, which of the following statements best describes the reaction? a The reaction is endergonic because it converts molecules with less free energy to those with more free energy. b The reaction is exergonic because it converts molecules with less free energy to those with more free energy. c The reaction is exergonic because it converts molecules with more free energy to those with less free energy d The reaction is endergonic because it converts molecules with more free energy to those with less free energy.arrow_forwardRelating to bioenergetics: a. The equilibrium constant for a particular reaction is 6.8 x 10-5 which makes this reaction exergonic. True or False?b. All processes that occur in the universe are spontaneous and have low enough activation energies that molecules can often overcome the energy barrier. True or False?c. ATP has a highly negative free energy change in part because the negative charges on the oxygens repel each other in ATP but less so in ADP. True or False?arrow_forwardWhat is an example where molecules or aroma within a cell physically overcome some barrier to their reaction going forward thag is exergonic one? (hint: think about what a catalyst physically does during a reaction).arrow_forward
- Compare the energy dynamics of a reaction at equilibrium with the dynamics of a reaction not at equilibrium.arrow_forwardEntropy increase A) with every reaction B) only in open systems C) only under certain reaction conditions D) only in the physical world. This cannot happen in cells otherwise cells would lose their needed energyarrow_forwardGeneral Biology 1 Explain the answers to A and B in great length (a couple of medium to long paragraphs). Give a coherent and relevant answer. A. What are the two forms of Energy? Give examples on each form. Hint: Mechanical energy, chemical energy, and electrical energy. B. Summarize the Laws of Thermodynamics.arrow_forward
