Enzyme catalysis definition

WebEnzymes are life’s great facilitators. They create the conditions needed for biochemical reactions to happen fast. The general name that chemists use for a chemical entity that increases the speed of a reaction is a “catalyst.” Enzymes are biological catalysts--they catalyze the chemical reactions that happen inside living things. WebEnzymes are substances found in biological systems that are catalysts for specific biochemical processes. Although earlier discoveries of enzymes had been made, a significant confirmation of their importance in living systems was found in 1897 by the German chemist Eduard Buchner, who showed that the filtered cell-free liquor from …
