Stored energy due to position is:
Energy of motion is:
Amount of disorder is the change in:
Temperature (thermal energy) increases the amount of ________ in the system
Total energy in a molecule is the change in:
Enthalpy is based on difference in _____ ______
What are the 2 basic chemical reactions?
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
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)
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)
Non-spontaneous reactions are:
- Endergonic, where ΔH is (+), ΔS is (-), and ΔG is +
- Requires input of energy
Spontaneous Reactions are:
- Exergonic, where ΔH is (-), ΔS is (+), and ΔG is -
- Net release of energy
Even spontaneous reactions need an initial input of energy to get
reaction going called:
______ are catalsys that speed up biological reactions by reducing the Activation energy required for spontaneous reactions to proceed.
Enzymes can be ______, and are specific to particular _________.
Enzymes bring reactants together and distort substrate bonds to bring to :
