    1. All reactions result in a change in free energy
    2. That disorder in the universe is always increasing
    3. Not all energy resulting from chemical reactions is available to do work
    4. Entropy is free energy, and enthalpy is energy lost to the system
    5. Endergonic reactions release energy
    1. Decrease activation energy
    2. Are biological catalysts
    3. Help metabolic processes proceed more rapidly
    4. Can work at an unlimited rate regardless of temperature substrate concentration and pH
    1. Decrease the temperature of the incubator where the cells are growing
    2. Increase the pH of the media the cells are growing in to the optimum pH
    3. Add cofactors to the media the cells are growing in
    4. Add an allosteric activator to the cells
    1. A metabolic pathway
    2. Feedback inhibition
    3. Allosteric regulation
    4. Enzyme inhibition
