WebA catalyst is part of a chemical reaction that does not get used up and lowers the activation energy. A cofactor is a helper for an enzyme to make the reaction go. Without it, the enzyme can not do its job (remember the enzyme is what lowers the activation energy for a reaction), so an enzyme is a catalyst thats a protein essentially. WebEnzymes are encoded as genes in the DNA — these genes are then transcribed to produce RNA and (for most enzymes§) then translated† to make a protein that has a catalytic activity (i.e. is an enzyme). Typically enzymes found within a cell are encoded …
