• Enzyme catalysis — is the catalysis of chemical reactions by specialized proteins known as enzymes. Catalysis of biochemical reactions in the cell is vital due to the very low reaction rates of the uncatalysed reactions. The mechanism of enzyme catalysis is similar …   Wikipedia

• Enzyme kinetics — is the study of the chemical reactions that are catalysed by enzymes, with a focus on their reaction rates. The study of an enzyme s kinetics reveals the catalytic mechanism of this enzyme, its role in metabolism, how its activity is controlled,… …   Wikipedia

• Enzyme — Biocatalyst redirects here. For the use of natural catalysts in organic chemistry, see Biocatalysis. Human glyoxalase I. Two zinc ions that are needed for the enzyme to catalyze its reaction are shown as purp …   Wikipedia

• Catalysis — Catalyst redirects here. For other uses, see Catalyst (disambiguation). Solid heterogeneous catalysts such as in automobile catalytic converters are plated on structures designed to maximize their surface area …   Wikipedia

• Enzyme substrate — In biochemistry, a substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate(s). The substrate binds with the enzyme s active site, and an enzyme substrate complex is formed. The substrate is… …   Wikipedia
