The process of weathering deals with the breaking down of minerals, soils and rocks as well as synthetic materials as a result of contact with the atmosphere, biological entities and water. Weathering is slightly different from erosion, because it does not involve movement. Erosion involves the movement of water, wind, snow or other agents across minerals or rocks. Weathering simply takes place “in situ.” There are two significant types of weathering, chemical and physical. Each can involve a biological component, but the difference is that physical weathering has to do with soils and rocks breaking down as a result of directly contacting ...

Introduction

Biological reactions are those reactions that are involved in various activities, in the body including energy production. Reactions that produce energy are called exergonic reactions while those that use energy are called endergonic reactions. Enzymes enable chemical reactions to take place within a living system most of which are under a homeostatic constraint. In these reactions, enzymes function as a catalyst by lowering the activation energy necessary in a reaction (Cooper, 2000). Enzymes bring the reactants involved in a reaction closer together weakening the chemical bonds and this enable the reactions to occur faster compared to reactions that have no enzyme (Farabee, 2010).
