Covalent catalysis enzyme
WebJan 13, 2015 · Enzyme motions on a broad range of time scales can play an important role in various intra- and intermolecular events, including substrate binding, catalysis of the chemical conversion, and product release. The relationship between protein motions and catalytic activity is of contemporary interest in enzymology. To understand the factors … 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.
