catalyst :- substance which increase the rate of reactoin without being get consumed in it.
enzyme :- boilogical catalyst which increase the rate of boilogical reaction
e.g. amaylase enzyme found in human saliva
sacrificial protection :- reduction of corrosion of a metal in an electrolyte by galvanically coupling it to a more anodic metal

a catalyst is a substance that's add to the reaction so that the process happens quicker but is not consumed during the reaction, you can still find it at the end.
enzymes are also catalyst but natural ones syntetised by the human body.
and I'm sorry but i don't know what sacr is

Catalysts r substances which alter the rate of chemical reactions without undergoing any overall chemical change themselves.
catalysts which bring abt biochemical changes in a chemical reaction r known as enzymes

catalysts doesn't get changed, but over time, they get "poisoned" and so they will need to be replaced in the end (after a long usage). They also reduce the activation energy required to start a reaction.

a catalyst is basically something that filters out harmful emmisions from vehicle exhausts, and is now required in all vehicles.
