Essay --

Aim To measure the amount of group O wipe outs in by the maggots and peas with the help of a respirometer in the experiment.IntroductionRespiration is the process by which organic molecules are broken down in a serial of stages to synthesize ATP.Respiratory quotient is a measure of the ratio between oxygen an organism takes in and ascorbic acid dioxide the organism eliminates. The use of a doodad called a respirometer is used to measure an organisms respiratory quotient by measuring the gases the organism takes in and exhales.Metabolism is all the chemical processes that take place in living organisms for example breathing, circulating blood and authoritative body temperature. Since the peas and maggots used in this experiment are living things, they could light upon the result since they both expire aerobically and take part in metabolism.With cellular respiration of carbohydrates, the food is then converted to carbohydrates usually hexose sugar before cosmos sighd. Ther e is an oxidation of glucose to carbon dioxide and water with the release of energy. Oxygen + glucose vitamin C dioxide + water + energy (in the form of ATP)When there is no use of oxygen it is anaerobic respiration and with usage of oxygen, this is aerobic respiration.In the presence of oxygen there are 4 stages namely glycolysis in the cytoplasm, link chemical reaction and Krebs cycle in the matrix of the mitochondria and electron ravish chain in the mitochondrial membranes. ATP is generated when H is lost and used to reduce coenzymes. The reduced atomic number 1 carrier can be used to generate ATP by oxidative phosphorylationIn the absence of oxygen the Krebs cycle and electron transport system cannot operate and only glycolysis takes place, which yields a two molecules for each(prenominal) g... ... in the sucrose solution contains carbohydrates. Food source would affect respiration, as each food source has a different energy values and respire in a different way.Appendices This is calculated starting with obtaining the amount of carbon dioxide released by subtracting value b from value a. The respiratory quotient is then ground by dividing the volume of carbon dioxide released over the volume of oxygen consumedPeasMaggots set (g)5.60-3.93=1.675.06-4.00=1.06Value (a) with KOH3.50-2.00=1.504.25-2.50=1.75Value (b) without KOH3.75-3.75=0.003.50-3.00=0.50Respiratory Quotient per unit1.000.711) Volume of CO2 remote by peas is a-b (1.50-0)=1.50RQ = (volume of carbon dioxide released)/(volume of oxygen consumed) RQ is 1.50/1.50=12) Volume of CO2 released by maggots is 1.75-0.50=1.25With the RQ value is 1.25/1.75=0.71
