Sommario/riassunto

This program outlines the essential features of enzymes and their vital role in all living cells. It discusses the function of a catalyst and enzymes as organic catalysts and looks at activation energy and enzyme structure. It illustrates the lock and key model of enzyme action, examines the roles of coenzymes and cofactors, and explores such factors affecting enzyme action as temperature, pH, enzyme concentration, and substrate concentration. It also looks at competitive and non-competitive enzyme inhibition and discusses enzymes and DNA.
