WebEnzymes are biological catalysts. Meaning they occur to help biological processes within our bodies occur (lower activation energy and increasing rate of reaction). Without enzymes, most of the essential reactions required for life (Glycolysis, krebs cycle, etc) would not be possible. 1 comment. WebCatalysis (/ k ə ˈ t æ l ə s ɪ s /) is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (/ ˈ k æ t əl ɪ s t /).Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and … gary nitsche attorney delaware
