Chemical Reactions
Definition:
Chemical Reactions & Energy:
When one or more substances change to produce one or more different substances.
Energy is always involved (released or absorbed)

Why is energy needed in a chemical reaction?
Energy is necessary to: Form bonds Break bonds
Endothermic Reactions: Absorb more energy than they release (form bonds)
Exothermic Reactions: Release more energy than they absorb (break bonds)

Energy & Chemical Reactions
Activation Energy:
How much energy?
The amount of energy needed to start a reaction.
For a living organism it is quite large, it would be a significant portion of their available energy.

Catalysts
Definition:
All for one and one for all?
A chemical substance that reduces the activation energy needed for a reaction.
Nope – there are many kinds of catalysts and they all work on different types of reactions.
