Activation Energy- amount of energy required for a chemical reaction t start and to continue on its own.
Catalyst- a chemical that reduces the amount of activation needed for a reaction but is not a reactant.
Endergonic reaction- a chemical reaction that involves a net absorption of free energy
Energy- the ability to do work or cause change
Enzyme- a catalyst, usually a protein, in living systems
Exergonic reaction- a chemical reaction that involves a net release of free energy
Free energy- the energy in a system available for work
Oxidation reaction- the chemical reaction in which the reactant loses one or more electrons, becoming more positive in charge
Product- a compound or atom involved in a chemical reaction
Reactant- a compound or atom involved in a chemical reaction
Redox reaction- a redox-oxidation reaction in which electrons are transferred between atoms
Reduction reaction- a chemical reaction in which a reactant gains one or more electrons, becoming more negative in charge.
State- solid, liquid, or gas, a state of matter
