V. HAZADOUS WASTE TREATMENT PROCESS Presently‚ the hazardous waste treatment technologies are highly developed from the decade before due to the more environmental and ecosystem concerning. Moreover‚ hazardous waste not threaten only environment but also to human hygiene and health. However‚ one of the most dangerous hazardous waste is dichlorodiphenyltrichloroethane (DDT). Addition‚ DDT is used as a majority pesticide during agriculture revolution period‚ and also uses to regulate Malaria in developing

endproduct. Respiration occurs in three major stages: 1) Glycolysis – occurs in the cytoplasm for both prokaryotic and eukaryotic cells • One glucose (6C) is broken into two 3C molecules – 2 pyruvic acids (pyruvate) • One oxidation step produces two molecules of reduced coenzyme – 2NADH • One step produces energy in the form of ATP – 2ATP • The pyruvic acids continue to the next stage – the Krebs Cycle • The 2 NADH proceed to the third stage –

The reaction can be written as: ATP ® ADP + Pi + energy The regeneration of ATP from ADP requires energy‚ which is obtained in the process of oxidation. The energy released in the oxidation of carbohydrates and fats initiates a complex series of chemical reactions that ultimately regenerate ATP molecules from ADP molecules. The complete oxidation of a typical molecule of fat results in the formation of about 150 molecules of ATP. ATP was discovered in muscle tissue by scientists in Germany and

release large amounts of energy. However‚ the energy release is uncontrolled. An organism would not be able to handle all that energy at once to do the work of the cell. Cellular respiration is essentially the same reaction as combustion‚ but the oxidation of glucose occurs in several controlled steps. The same amount of energy is ultimately released‚ but it is gradually released in small‚ controlled amounts. High potential energy molecules of ATP are produced while the carbon atoms are used to form

Chronoamperometry is one of several electrochemical techniques which quantify the oxidation or reduction current of electroactive molecules at an electrode. Oxidation or reduction can be induced by changing the applied voltage at the working electrode. The concentration of the electroactive molecules is proportional to the current produced by their oxidation or reduction‚ which allows one to determine the concentration of electroactive neurotransmitters and other biological molecules of interest

INTRODUCTION Chemical reactions are regularly categorized into 3 types: oxidation-reduction (redox reaction)‚ precipitation (double displacement) and acid-base reaction (double displacement) Type 1: Oxidation-Reduction Reactions Oxidation-reduction processes include the movements of electrons form oxidants to reductants‚ which lead to increases in oxidation number for oxidised species and decreases in oxidation number in reducing species. A. Synthesis Reactions: 2 (or more) substances react

Macronutrients‚ Oxidation and Energy Fats‚ carbohydrates and proteins are regarded as macronutrients because the body usually extracts other nutrients from them. In addition to supporting body growth‚ development and repair‚ macronutrients give us energy. This energy is measured in calories. When fat‚ carbohydrate and protein undergo oxidation‚ carbon-dioxide‚ water and energy are released. But according to Cleveland Clinic‚ fat
