Resource summary

Cell Transportation
1 Enzymes (Type 1)
1.1 Catalysts: Speeds up reactions without being used up themselves
1.1.1 Energy of Activation: the amount of energy the reactants must absorb to become activated and start a chemical reaction
1.1.1.1 Endergonic Reactions
1.1.1.2 Exergonic Reactions: a reaction that releases energy
1.2 Active Site: 3-D site that substrate will bind to
