Biological catalysts Study guides, Class notes & Summaries

Catalyst - 1. Chemical or biological substance or structure that lowers activation energy 2. Accelerates the rate of a chemical rxn Enzymes - Biological catalysts that are capable of performing multiple rxns (are recycled). They can be proteins or RNA, are faster than chemical catalysts, and act under mild conditions (bodily temperature/pressure). They are highly specific and tightly regulated. Enzyme functions - - cell shape and motility - surface receptors - metabolism - cell cycling ...

I. Enzymes and coenzymes. Regulation of metabolism. 1. Enzymes: definition, structure and properties of enzymes. - Enzymes definition are biological catalysts, which determine the rate and pattern of chemical transformations in biological systems that underlie the meta- bolic pathways. According to their chemical nature, all the enzymes are pro- teins. Shortly speaking, enzymes are designated as biological catalysts of a protein nature. Under the catalytic action of enzymes biomolecules (s...
