The sum total of all the chemical reactions in a living structure is called its:
Water held back by a dam represents what kind of energy?
What can never be created or destroyed?
Which of the following represents potential energy?
A. Chemical bonds
B. Concentration gradient
C. Electric charge imbalance
D. Both a and b
E. All of the above
The first law of thermodynamics states that the total energy in the universe is
In any system, the total energy includes usable and unusable energy. The unusable energy is a measure of the disorder of the system and is referred to as
A change in free energy is related to a change in
If G of a chemical reaction is negative and the change in entropy is positive, you can conclude that the reaction is
The standard free energy change for the hydrolysis of ATP to ADP + Pi is –7.3 kcal/mol. From this information one can conclude that the reaction is
Chemical equilibrium is a state in which G =
When ADP gains a phosphate to form ATP, energy is
If the enzyme phosphohexosisomerase is added to a 0.3 M solution of fructose 6-phosphate, and the reaction is allowed to proceed to equilibrium, the final concentrations are 0.2 M glucose 6-phosphate and 0.1 M fructose 6-phosphate. These data give an equilibrium constant of 2. What is the equilibrium constant if the initial concentration of fructose 6-phosphate is 3 M?
