Energy is essential for normal body functioning processes thus it is generated from glucose metabolism in an enzymatic chemical reactions. This yields energy as well as carbon dioxide after utilizing the glucose and oxygen. This cellular respiration is usually affected by various factors such as availability of oxygen without which anaerobic respiration takes place, availability of water, protoplasmic environment, temperature and carbon dioxide concentration.
In this particular experiment, the procedure is carried out at different temperatures starting with 4˚C, 24˚C and then 37˚C while measuring the amount of oxygen utilized and that of carbon dioxide generated and the values recorded to plot a bar graph presentation.

This process involves chemical reactions at the cell organelles, mitochondria. (Campbell and Paradise, 2016) These chemical processes and the enzymatic reactions can be summarized by the following equation for glucose breakdown.
〖 C〗_6 H_12 O_6+O_2=〖CO〗_2+H_2 O+686kc.
A number of methods to determine the amount of energy produced and the quantities of oxygen and carbon (IV) oxide used and consumed respectively have been put in place. These can be calculated by the use of oxygen sensor as well as carbon (IV) oxide sensor.
There is a difference in the amount of Oxygen utilized as well the amount of Carbon dioxide produced during respiration under different conditions for germination. There are several factors that bring about this difference ranging from the amount of oxygen contents, availability of water, variation in temperature, protoplasmic factors as well carbon dioxide concentration. In this particular experiment, temperature and water availability are the major factors under

The garbanzo beans were placed in a 100ml beaker prechilled to 4˚ C and sitting on ice to maintain the temperature. The respiration chamber as filled it hater and then emptied. The respiration chamber was then thoroughly dried using a paper towel. The chamber as placed on the ice and left for five minutes into which the garbanzo beans were placed and then left for 5 minutes. A linear regression as performed to calculate the respiration rate. A Fit curve as chosen from the Analyze menu and carbon (IV) oxide, the Linear as selected as the FIT Equation by
y=mx+b.
The absolute value of the slope, m, was then entered as the rate of respiration for the carbon (IV) oxide Gas Sensor in Table 2 then Ok as selected. The rate of respiration as calculated for oxygen Gas Sensor by choosing the Curve Fit from Analyze menu and oxygen gas selected. Linear as selected as the Fit Equation, y=mx+b The absolute slope, m, as then entered as the rate of respiration for oxygen gas sensor in Table 2. Okay as then
Cellular respiration is the process by which energy is harvested involving the oxidation of organic compounds to extract energy from chemical bonds (Raven & Johnson, 2014). There are two types of cellular respiration which include anaerobic respiration, which can be done without oxygen, and aerobic respiration, which requires oxygen. The purpose of this experiment is to determine whether Phaseolus lunatus, also known as dormant seeds or lima beans, respire. You will compare the results of the respiration rate of the dormant seeds, and the Pisum sativum, or garden peas. In this experiment, you will use two constants which will be the temperature of the water and the time each set of peas are soaked and recorded. Using these constants will help

Cellular respiration is a chemical reaction used to create energy for all cells. The chemical formula for cellular respiration is glucose(sugar)+Oxygen=Carbon Dioxide+Water+ATP(energy) or C6H12+6O2=6CO2+6H2O+ energy. So what it is is sugar and

The results of this experiment are shown in the compiled student data in Table 1 below.
The Effect of Temperature on the Activity of the Enzyme Catalase Introduction: The catalase is added to hydrogen peroxide (H²0²), a vigorous reaction occurs and oxygen gas is evolved. This experiment investigates the effect of temperature on the rate at which the enzyme works by measuring the amount of oxygen evolved over a period of time. The experiment was carried out varying the temperature and recording the results. It was then repeated but we removed the catalase (potato) and added Lead Nitrate in its place, we again tested this experiment at two different temperatures and recorded the results. Once all the experiments were calculated, comparisons against two other groups were recorded.
The data which was collected in Procedure A was able to produce a relatively straight line. Even though this did have few straying points, there was a positive correlation. This lab was able to support Newton’s Law of Heating and Cooling.
In order to determine a system curve the flow rate must be determined at a range of points. Plotting both the system curve and pump curve together enables the operating point to be found which corresponds to the ideal flow rate. The pump curve can be determined experimentally by modifying the system curve one of two ways; either opening a valve or changing the height difference.
Our predicted points for our data are, (13, -88.57) and (-2, -29.84). These points show the
By using this principle, the measurement of an organism's volume if it absorbs CO2 released in respiration can be attributed to the consumption of oxygen. Hypothesis: If the temperature increases, then the respiration rate will also increase. The respiration rate will increase because more activity is going on. Experiment: A simple respirometer will be used in this experiment to detect changes in gas volume.
In our Biology Lab we did a laboratory experiment on fermentation, alcohol fermentation to be exact. Alcohol fermentation is a type of fermentation that produces the alcohol ethanol and CO2. In the experiment we estimated the rate of alcohol fermentation by measuring the rate of CO2 production. Both glycolysis and fermentation consist of a series of chemical reactions, each of which is catalyzed by a specific enzyme. Two of the tables substituted some of the solution glucose for two different types of solutions. They are as followed, Table #5 substituted glucose for sucrose and Table #6 substituted the glucose for pH4. The equation for alcohol fermentation consists of 6 Carbons 12 Hydrogens 6 Oxygen to produce 2 pyruvates plus 2 ATP then finally the final reaction will be 2 CO2 plus Ethanol. In the class our controlled numbers were at Table #1; their table had 15 mL Glucose, 10 mL RO water, and 10 mL of yeast which then they placed in an incubator at 37 degrees Celsius. We each then measured our own table’s fermentation flasks every 15 mins for an hour to compare to Table #1’s controlled numbers. At

According to our text, Campbell Essential Biology with Physiology, 2010, pg. 78. 94. Cellular respiration is stated as “The aerobic harvesting of energy from food molecules; the energy-releasing chemical breakdown of food molecules, such as glucose, and the storage of potential energy in a form that cells can use to perform work; involves glycolysis, the citric acid cycle, the electron transport chain, and chemiosmosis”.
When humans consume plants, the carbohydrates, lipids, and proteins are broken down through two forms of cellular respiration. The two processes of cellular respiration displayed in humans are anaerobic and aerobic. The deciding process used depends on the presence of oxygen. Cellular respiration converts the material into a useable energy called ATP. ATP is the energy form that cells can use to perform their various functions, and it can also be stored for later use.
