The activation energy needed for a chemical reaction is decreased by a

• catalyst

• reactant

• product

• substrate

If the activation energy of a biochemical reaction is lowered, then

• the reaction will happen faster

• the reaction will happen more slowly

• this will not affect the rate of the reaction

• both A and B
