Define the term biological catalyst
WebThese days we encounter the concept of a catalyst most often in connection with technology for cleaning up the exhaust fumes from our automobiles, where platinum and rhodium catalyze the breakdown of polluting nitrogen oxides. Chemical reactions within living cells must also be catalyzed. Biological catalysts are called enzymes. WebFeb 27, 2024 · The catalyst just changes the path to the new chemical partnership. It builds the equivalent of a paved highway to bypass a bumpy dirt road. A catalyst doesn’t get used up in the reaction, though. Like a wingman, it encourages other molecules to react. Once they do, it bows out. Enzymes are biology’s natural catalysts.
