  1. Stored energy due to position is:
    Potential Energy
  2. Energy of motion is:
    Kinetic Energy
  3. Amount of disorder is the change in:
    Entropy
  4. Temperature (thermal energy) increases the amount of ________ in the system
    disorder.
  5. Total energy in a molecule is the change in:
    Enthalpy
  6. Enthalpy is based on difference in _____ ______
    Heat content
  7. What are the 2 basic chemical reactions?
    Spontaneous, Non-spontaneous
  8. Explain Spontaneous Reactions
    Energy is released (Exergonic) which means a decrease in potential energy (enthalpy) and increase in entropy, This is a (Catabolic) breakdown reaction. Catabolic
  9. Explain Non-Spontaneous Reactions
    Energy must be absorbed into system (Endergonic) which means an increase in potential energy (enthalpy) and a decrease in entropy. This is a Synthesis reaction or Anabolic (builds up)
  10. What is Gibb's Free Energy Change of a Reaction?
    • ΔG = ΔH - T ΔS
    • (ΔG- Change in energy)
    • (ΔH- Change in Enthalpy)
    • (ΔS- Change in Entropy)
    • (T  - Temperature)
  11. Non-spontaneous reactions are:
    • Endergonic, where ΔH is (+), ΔS is (-), and ΔG is +
    • Requires input of energy
  12. Spontaneous Reactions are:
    • Exergonic, where ΔH is (-), ΔS is (+), and ΔG is -
    • Net release of energy
  13. Even spontaneous reactions need an initial input of energy to get
    reaction going called:
    Activation Energy
  14. ______ are catalsys that speed up biological reactions by reducing the Activation energy required for spontaneous reactions to proceed.
    Enzymes
  15. Enzymes can be ______, and are specific to particular _________.
    reused, substrates.
  16. Enzymes bring reactants together and distort substrate bonds to bring to :
    Transition State
