Which of the following statements about the combustion of glucose with oxygen to form water and carbon dioxide (C6H12O6 + 6 O2 → 6 CO2 + 6 H2O) is correct?
The entropy of the products is greater than the entropy of the reactants.
Which of the following statements about equilibrium of chemical reactions is correct?
A) The equilibrium point is where the system has the highest free energy B) Reactions can only go in the direction toward equilibrium. C) A reaction that is at equilibrium is not capable of doing any work.
C) A reaction that is at equilibrium is not capable of doing any work.
Which of the following statements about ATP (adenosine triphosphate) is correct?
The cycling between ATP and ADP + Pi provides an energy coupling between catabolic and anabolic pathways -Catabolic pathways provide the energy needed to make ATP from ADP and Pi. The hydrolysis of ATP to ADP + Pi releases the same amount of energy.
