Enzymes principles and biotechnological applications

Nov 15, · Enzymes are potent catalysts. The enormous catalytic activity of enzymes can perhaps best be expressed by a constant, k , that is variously referred to as the turnover rate, turnover frequency or turnover number.This constant represents the number of substrate molecules that can be converted to product by a single enzyme molecule per unit time (usually per minute or per second).

Types of metal used. Many of the first metal artifacts that archaeologists have identified have been tools or weapons, as well as objects used as ornaments such as jewellery.These early metal objects were made of the softer metals; copper, g, and lead in particular, as the metals either as native metal or by thermal extraction from minerals, and softened by minimal heat (Craddock, 1995).
