endergonic
a chemical reaction that has a positive G is correctly describes as
25/1000= .025-- 298*.25---= -897.45
assume that temperature is 298 K, calculate G, when H is -890 kJ/mol and S is 25 J/K
G is the change in free energy
the mathematical expression for the change in free energy of a system is delta G=H-T*S. Which of the following is (are) correct?
it is lost to the environment
when chemical, transport, or mechanical work is done by an organism, what happens to the heat generated
entropy of the universe
whenever energy is transformed, there is always an increase in the

which of the following best describes enthalpy (H)
energy cannot be created or destroyed
which of the following is a statement of the first law of thermodynamics
the reaction proceeds with a net release of free energy

metabolism consists of all the energy transformation reactions in an organism
which of the following is true of metabolism in its entirety in all organisms
catabolism
which term most precisely describes the cellular process of breaking down large molecules into smaller ones
