Essay --

Aim To measure the amount of oxygen takes in by the maggots and peas with the help of a respirometer in the experiment.Introduction cellular respi proportionalityn is the process by which organic molecules are broken down in a series of stages to synthesize ATP.Respiratory quotient is a measure of the ratio between oxygen an organism takes in and carbon dioxide the organism eliminates. The apply of a device c all(prenominal)ed 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, go blood and controlling body temperature. Since the peas and maggots used in this experiment are living things, they could view the result since they both expire aerobically and take sectionalisation in metabolism.With respiration of carbohydrates, the food is then converted to carbohydrates usually hexose scrape before being respir ed. There is an oxidation of glucose to carbon dioxide and water with the emission of postcode. Oxygen + glucose Carbon 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 reaction and Krebs musical rhythm in the matrix of the mitochondria and electron enamour chain in the mitochondrial membranes. ATP is collapsed when H is lost and used to inhibit coenzymes. The reduced Hydrogen 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 cardinal molecules for each 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.AppendicesT his is calculated scratch with obtaining the amount of carbon dioxide released by subtracting value b from value a. The respiratory quotient is then found by dividing the loudness of carbon dioxide released over the volume of oxygen consumedPeasMaggotsMass (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) flock of CO2 removed 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) playscript of CO2 released by maggots is 1.75-0.50=1.25With the RQ value is 1.25/1.75=0.71
