The Action of Naturally Occurring Toxins and Medicines It is important to classify toxins and medicines (drugs) in order to understanding the mechanism and function of each one of them. By doing so‚ it is also possible to increase their values by altering their mechanism (e.g. converting toxins to drugs) to cure diseases and improve human health. Therefore in this review‚ the mode of action of several toxins and drugs as well as their effects on human body will be discussed. 1. Cobratoxin Cobratoxin

The primary xylem and primary phloem tissues are pushed inward into the] pith and outwards respectively by the continuous production of secondary tissues cut I off by the cambium ring. The primary xylem is gradually pushed inward and is found at the centre of the axis; whereas‚ the primary phloem‚ being soft in nature‚ gets completely crushed. These activities in the stelar region exert a great pressure outwardly. The cortex cells‚ the pericycle and the epidermis divide anticlinally to cope

do so at a specific time during the life cycle of the cell. These antimicrobial drugs are produced during the stationary phase of the cycle. The cells are not growing and dividing rapidly at this point‚ therefore they produce secondary metabolites. Secondary metabolites are produced after the initial exponential growth segment. This is part of the bacterial growth curve (Todar 2011). The term penicillin makes reference to the vast collection of related antibiotics. Each member of the penicillin

Consumer: 1. Animals that eat ONLY PLANTS They are called Primary Consumers. 2. Animals that eat OTHER ANIMALS * Carnivores that eat herbivores are called secondary consumers. * Carnivores that eat other carnivores are called tertiary consumers. * Predators - kill for food. They are either secondary or tertiary consumers – e.g. Tigers‚ Eagles * Prey - are the organisms that predators feed on. Examples of predator and prey species are: fox and rabbit; bird and caterpillar;
