Biochemical Pathways of Heavy Metals Poisoning BIO101 (Principles of Biology) 6 July 2012 Abstract The biochemical pathways of heavy metal poisoning are routes by which the metals pass in the body as they impair and destroy normal cellular and organ activity. The most common types of heavy metal poisoning are caused by lead‚ arsenic‚ cadmium and mercury. They are also the most extensively studied at the moment. Lead poisoning occurs mainly by the inhibitory effect that the metal imposes on enzymes

1. EGG INOCULATION The fertile hen’s egg can be used to cultivate and propagate various types of viruses. Because of the ability to alter their tropism and to adapt to a new host species‚ many viruses become capable of growing in chick embryo tissues wherein they frequently attain a much higher concentration than in the tissues of the natural host. STRUCTURE OF AN EGG The extra-embryonic membranes of the chick embryo arise from three germinal layers: the endoderm‚ mesoderm and ectoderm

1. What are antibodies and why are antibodies ideal for targeting? An antibody‚ also known as an immunoglobulin‚ is a large Y-shaped protein used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. The antibody recognizes a unique part of the foreign target‚ termed an antigen.[1][2] Each tip of the "Y" of an antibody contains a paratope (a structure analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen

reactants can be brought together to react. These reactants are called substrates that fin into the enzyme. The changing of heat‚ surface area‚ chemicals‚ and pH will denature the shape of the enzyme‚ not allowing it to do its function. Testing on peroxidase- an enzyme- will be done on an animal enzyme (chicken liver) and a plant enzyme (potato). For testing Hydrogen Peroxide (H2O2) will be poured over the enzymes. When the enzymes in the potato or liver combine with the substrate Hydrogen Peroxide

Amee Kelley Sparace Biology 102 5 October 2011 The Commercial Uses of Lignin and Suberin Plants have a way of teaching humans how to better the world around them. They create and use “green” products and chemicals everyday that we as a society are just starting to learn how to use to make our lives greener. We can also use these chemicals to help keep our crops healthy and reduce our dependence on other countries. Lignin and Suberin are becoming more popular in the manufacturing world
