It was hypothesized that as temperature increases, the rate of respiration will increase as well. Data in this experiment does not support it fully. As the temperature increased from 0°Celsius to 20°Celsius to 43°Celsius, the rate of respiration increased as well (Figure 4). However, at 74°Celsius, the rate of respiration was at the lowest (Figure 4). Cellular respiration may increase as temperatures increases up to a limit. At 74°Celsius, the temperature may have been too high for the enzymes involved in the reaction, which will cause denaturing. Denaturing is when the conditions are outside the enzyme’s range and causes the enzyme to unfold, which means there is no activation site, and the substrate cannot bind to the enzyme, so the reaction is slowed down or stopped completely. If the temperatures were increased beyond the highest temperature tested, 74°Celsius, there respiration rate would stop completely. Additionally, at 0°Celsius, there is no cellular respiration occurring because the temperature is too cold for the cells (Figure 4). …show more content…
The dye moved toward the respiration chamber because the respiration rate has decreased. The dye would have moved away from the respiration chamber if the respiration rate has increased. The compensation chamber served at the control for the experiment because there were plastic beads inside, and plastic does not undergo respiration. Oxygen is vital in the cellular respiration process because it is an aerobic respiration process. Besides glycolysis, all the steps in cellular respiration need oxygen to proceed (OpenStax 2012). In the last stage of cellular respiration, the electron transport chain, oxygen served as the last acceptor of electrons and forms water (OpenStax 2012). To convert the respiration rate to a volume of oxygen consumed, the change in mm must be

Cellular Respiration Lab Report

Cellular Respiration is the reverse process of photosynthesis, in which glucose is broken down into ATP. There are three steps in this process, Glycolysis, Kreb’s Cycle, and Electron Transport Chain. A total of 36 ATP is produced during this process. The Overall Equation is: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP Glucose Oxygen Carbon Water Usable Dioxide Energy Step 1 : Glycolysis…

Cellular Respiration Lab Report

Explain why a simple exergonic free energy diagram would not be sufficient for cellular respiration with the following equation: C6H12O6 + 6O2 → 6CO2 +6H2O + 36 ATP That shows the overall process of oxidation of glucose to release energy. Not really sure of the question/answer. In terms of the cell respiration intermediary molecules, explain where the all the carbon atoms (C) in CO2 comes from when you exhale. Be specific. CO2 which usually takes glucose and oxygen which produces carbon dioxide…

Cellular Respiration Alyssa R Whitcher Hodges University Biology 1121 Mark Clifton 21 April 2015 Cellular Respiration Introduction: Cellular respiration is a series of metabolic processes by which living cells produce energy through the oxidation of organic substances. The harvesting of energy from glucose by cellular respiration is a cumulative function of three metabolic stages: Glycolysis, pyruvate oxidation, and oxidative phosphorylation. Glycolysis takes place in the cytosol of the…

ENGLISH PAPER

Lab Report 1 In this lab report we will be conducting an experiment to test for cellular respiration in germination. When germination occurs cellular respiration provides plants with the ATP needed to produce all the molecules that they require to grow. So in the experiment that follows serves for the purpose of measuring the amount of oxygen uptake and use that as proof that germinating soy beans are in fact carrying on cellular respiration. My hypothesis of course being that soybeans do in fact…

2O Cellular Respiration Lab Report Introduction Cellular respiration is the breaking down of food molecules and converting them into energy. Glucose is oxidized as long as there is the presence of oxygen and if not, fermentation will begin to take place. All organisms, including plants and animals, go through cellular respiration. This process creates energy for the body to exert in the form of ATP. This lab is to test if peas go through cellular respiration before germination. Hypotheses Part I:…

Develop An Understanding Of The Metric System

Lab Report 1 Purpose To develop an understanding of the metric system and use it to measure common objects. To also learn about how to report uncertainty in your measurements. Lab Observations Most flat objects do not consist of uncertainty. When we measured round objects, because of its shape, it contained uncertainty. Lab Answers 1. Using a metric ruler, determine the length of the items in Table 1.1 below: In the final column, you are to estimate your measurement precision. To do…

Post Mortem Examination

might be the case with someone who was decapitated, but the internal examination of the body is also important. The major organs of the body such as the heart, liver, lungs, and stomach are removed for examination, and small samples are taken for lab inspection. Indicators of disease are noted, and usually the stomach is opened so that its contents can be examined. Samples of body fluids are also taken so that they can be tested for drugs, toxins, and any other unusual substances. While the process…
