Anabolism and Catabolism Anabolism and catabolism are two phases of the human body’s metabolic process. Metabolism is a process that is essential for humans to live a healthy and productive life. The anabolism phase is the process where the body builds up the needed molecules. This phase requires energy in order to complete the process. Catabolism releases energy that can be used by the organism. This phase is the process of breaking down the complex molecules into smaller portions. These two

classes of polymers based on how the mers are joined together. * Addition – mers joined without the loss of atoms (presence of unsaturated carbons). * Condensation – mers joined through the loss of atoms from the functional groups of each monomer. Radioactive isotopes: * Everything with an atomic number over 82 is radioactive. * Unstable nuclei; too many neutrons:protons‚ large nuclei * Cobalt 60 formed by neutron bombardment. Detection: * Photographic film – exposes film

Mitzie Sowell Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. A DNA molecule which is abbreviation for deoxyribonucleic acid is made up of very long chains of monomers and polymers that are called nucleotides. These two chains in particular which composes of DNA strain are then formed by the grouping of the nucleotides into the polynucleotides. The nucleotide is made up of a nitrogenous base‚ of sugar and of

petroleum and natural gas. The manufacturing of plastic bags accounts approximately 4 per cent of the world’s total oil production (Greenfeet‚ 2004). Components of oil or natural gas are heated which creates hydrocarbon monomers. In the manufacturing process‚ hydrocarbon monomers are manipulated‚ resulting in the creation of hydrocarbon polymers (Greenfeet‚ 2004;

Abstract Enzymes are biological catalysts that speed up the rate of chemical reactions by lowering the reactants’ activation energy. The goal of this lab was conducted to determine the optimal temperature for bacterial and fungal Amylases and evaluate how temperature affects the catabolic rate of enzymes. Enzyme reaction rate was measured using an Iodine test in which drops of starch solution with either fungal or bacterial Amylase exposed to different temperatures were mixed with Iodine. Iodine
