Define Enthalpy: (H)
Heat contents of a system
Define Entropy: (S)
Randomness or disorder of a system
What does, "the total energy of system and its surroundings is constant" define?
1st Law of thermodynamics
What are the only 2 ways to transfer energy?
Heat (q)
Work (w)
what is the 2nd law of thermodynamics?
Total entropy of a system and its surroundings always increases for a spontaneous process
What happens to all irreversible processes in which a system is not in an equilibrium state?
changes spontaneously until it reaches equilibrium state?
what is occuring in a system with a change in G = 0
Reversible system (ie equilibrium)
how does a reaction with a change if G < 0 occur?
Spontaneous change at constant temperature and pressure
how does a system with a change in G > 0 change?
change can only occur if work is done on the system (i.e. it is not spontaneous)
What type of metabolic process occurs -change in G
Catabolic (break down molecules)
Exergonic (produce energy)
What type of metabolic process occurs during +change in G
Anabolic (building up of cells)
Endergonic (absorb energy)
Max energy you can get out in ideal conditions
-change in G
Minimum amount of energy you need to put into a system under ideal conditions
+change in G
What does ATP stand for?
adenosine triphosphate
What type of bonds are between the triphosphate molecules
Phosphoanhydride bonds
Are fatty acids or carbohydrates more efficent fuels
Fatty acids
In a redox reaction the atom that lose and electron is?
oxidized
In a redox reaction the atom gaining an election is?
reduced
what type of reaction occurs from one molecule rearranging into another with the same atoms
Isomerization
What does a group transfer reaction entail
The transfer of a functional group from one molecule to another
What type of reaction occurs when an atom, molecule, or ion reacts with water?
Hydrolytic reactions (hydrolysis)
Addition of Functional Groups
A reaction where gunctional groups are either added to double bonds or removed to form double bonds
