Activation energy is lowered to speed up a chemical reaction.
Catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction (or the rate of the reaction) increases.
A catalyst can speed up a chemical reaction.

to speed up a chemical reaction
A catalyst is used to SPEED up a reaction but doesn't change itself.
Anything that is added to a chemical reaction that's intended to speed up the reaction - is a catalyst.
Enzymes speed up a reaction by lowering the activation energy. This is the amount of energy required to start the reaction. By lowering the activation energy, the reaction can proceed much more quickly.
