Catalysts facilitate chemical reactions by lowering the activation energy required for the reaction to occur, but they remain unchanged in the process, which means they do not change their molecular structure. Option C is incorrect because inhibitors inhibit chemical reactions instead of facilitating them. Option D is incorrect because catalysts occur in biological systems as well, such as enzymes.
