Cellular Respiration Lab Report

Respiration was measured in germinating seeds in the Pea Lab because in germinating peas there is a high rate of cell respiration as the pea is still growing and needs to consume oxygen to continue growing. Pea plant cells rely on the process of cellular respiration to supply them with the energy that they need to stay alive and grow during germination. When the pea plants are grown the cells will still remove energy from sugar via cellular respiration; however, the sugar for cellular respiration will come from the process of photosynthesis instead of the stored

There are many procedures during this lab and many materials needed for an accurate analysis of data. First, fill a 100 mL graduated cylinder with 50 mL of water. Add 25 germinating peas and determine the amount of water that is displaced. Record this volume of the 25 germinating peas, then remove the peas and put those peas on a paper towel. They will be used for the first respirometer. Next, refill the graduated cylinder with 50 mL of water and add 25 non-germinating peas to it. Add glass beads to the graduated cylinder until the volume is the same to that of germinating peas. Remove the beads and peas and put on a paper towel. They will be used in respirometer 2. Now, the graduated cylinder was filled once again, determine how many glass beads will be require to reach the same volume of the germinating peas. Remove the beads and they will be used in respirometer 3. Then repeat the procedures used above to prepare a second set of germinating peas, dry peas and beads, and beads to be used in respirometers 4,5,and 6, the only difference is the temperature of the water.

The Effect of Temperature on Animal Respiration Renee King 001420538 TA: Oliver Biology 3U03 L01 This lab examined the effect of temperature on the rate of oxygen consumption by measuring VO2. Effects were observed in goldfish, frogs, and mice, which each use different mechanisms for thermoregulation. The average rate of oxygen consumption by goldfish increased from an average of 0.175 mL g-1 h-1 at 5֯ C to 0.288 mL g-1 h-1 at 25 ֯C which was a 64% increase. The average rate of oxygen consumption by the frog was higher at 5֯ C than at 25 ֯C. At both temperatures, the rate of oxygen consumption increased over time.

In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease in atmospheric pressure or temperature changes. There is a direct relationship between oxygen consumption and Carbon Dioxide produced, therefore the more O2 consumed the more CO2 produced. To keep the amount of CO2 produced from canceling out any pressure gained or lost from the consumption of

Cellular respiration is the series of metabolic process by which living cells produce energy through the oxidation of organic substances. Cellular respiration takes place in the mitochondria. Fermentation is the process by which complex organic compounds such as glucose, are broken down by the action of enzymes into simpler compounds without the use of oxygen. The significance of these pathways for organisms is to allow for an organism to be able to generate ATP. Some organism that undergo cellular respiration are bacteria and fungi. Some organism that undergo fermentation are yeast and muscle cells. In cellular respiration, glucose is oxidized and releases energy. In cellular respiration, glucose produces ATP and 3-carbon molecules of pyruvate. The pyruvate is then further broken down in the mitochondria where it becomes oxidized and releases CO2 (Upadhyaya 2014). In the fermentation process oxygen does not play a part. This process converts glucose into pyruvate and produces ATP. From there pyruvate breaks down into CO2 and acetaldehyde (Upadhyaya 2014) Monosaccharides are known as simple sugars and their main function is being the source of energy for organisms. Disaccharides are two monosaccharides joined by a covalent bond and their primary function is to provide food to monosaccharides. Some disaccharides

The Purpose of this experiment was to determine the importance of cellular respiration in the processes of Life. The objective of this experiment was to determine the rate of cellular respiration and how the presence of carbohydrates and pollutants will affect it. Our hypothesis was that an organism has larger rate of Cellular Respiration with the source of Carbohydrates as compared to the one that is without the Carbohydrates source and vice versa in

The two hypotheses tested during the experiment were the warmer the temperature, the more oxygen will be consumed, and the germinated peas will consume more oxygen than the dry peas. Some conditions that had to remain constant in this experiment were that each vial had to have the same volume to let us know that the volume of the vial wouldn’t affect the respiration rate. Had the volumes been different, the respiration rate might have been affected. Another constant was the 7 minute equilibrium period before completely submerging the vials in the water. This allowed the peas and the other substances in the vials to begin respiration before being completely submerged in the water, but also, they would have the same time to carry out

This experiment consisted of 3 respirometers, one with ants, one with radish seeds, and one with glass beads. Each with 4 pellets of KOH and a piece of cotton. They were placed in a water bath that was at 75 degrees fahrenheit. A bubble at the end of the respirometer was measured every five minutes, and this distance showed how well the organisms were respiring. The radish seeds were able to do the most cellular respiration in 25 minutes, with the ants being a close second, and the control respirometer of the glass beads doing the least.

This lab deals with the transpiration rates in plants, specifically a tomato plant that was used for this experiment. Transpiration is when water leaves a plant through the stomata as water vapor while the stomata is capturing CO2 for photosynthesis. This experiment used three different scenarios: a tomato plant with a light shining on it, a tomato plant with wind blowing on it from a fan, and lastly a tomato plant with nothing acting on it. The hypothesis is that the rate of transpiration will be fastest with light, faster with wind, and slow with the control. This hypothesis was rejected because the rate of transpiration is as follows with the wind having the fastest rate: with light the rate was 7.60 mm/min, with wind 10.20 mm/min, and control 4.33 mm/min. The cause of the wind having a faster transpiration rate than the light may have been due to the surface area of the leaves on the tomato plants. The surface area of the leaves for the wind experiment is 8,124mm2, and for the light is 7,740mm2.By doing this transpiration experiment it helps one to see what happens in plants daily and understand why it happens.

Cellular respiration is a procedure that most living life forms experience to make and get chemical energy in the form of adenosine triphosphate (ATP). The energy is synthesized in three separate phases of cellular respiration: glycolysis, citrus extract cycle, and the electron transport chain. Glycolysis and the citric acid cycle are both anaerobic pathways because they do not bother with oxygen to form energy. The electron transport chain however, is aerobic due to its use of oxidative phosphorylation. Oxidative phosphorylation is the procedure in which ATP particles are created with the help of oxygen atoms (Campbell, 2009, p. 93). During which, organic food molecules are oxidized to synthesize ATP used to drive the metabolic reactions necessary to maintain the organism’s physical integrity and to support all its activities (Campbell, 2009, pp. 102-103).

All living organisms need the energy to perform the basic life functions. Cells use a process called cellular respiration to obtain the energy needed. In cellular respiration, cells convert energy molecules like starch or glucose into a cellular energy called Adenosine triphosphate(ATP). There are two types of cellular respiration which include: Aerobic and Anaerobic respiration. In aerobic respiration, cells will break down glucose to release a maximum amount of ATP this takes place in the presence of oxygen. Aerobic also produces carbon dioxide and water as waste products and it takes place in the mitochondria. on the other hand, anaerobic respiration, a metabolic process, also produces energy and uses glucose, but it releases less energy and does not require the

The Effect of Activity on a Human’s Cellular Respiration Rate Introduction: Cellular respiration is a process that breaks down glucose forming ATP, and releasing CO2 as a by product (“Cellular Respiration”). Cellular respiration is main source of energy in for humans. Since it produces CO2 as a by product, by testing CO2 rates, one can determine the metabolic or cellular respiration rate of a human. Our experiment was testing human activity rate on cellular respiration rate.

TABLE 1: This table represents the lung capacity of people who do exercise constantly, their lung capacity was measured with the balloon who after that was introduce into the bucket and water was represented en ml in the table below.

Abstract: The purpose of this experiment was to evaluate the effect of varying environmental factors on the rate of transpiration. We decided to test the factor of light, and what the rate of transpiration is before and after taking away sunlight. We found that the rate of this process was relatively the same in both the light and the dark areas of the classroom.

In this lab report, the hypothesis that both animal and plant cells go through cell respiration was tested in a lab setting. The test compared the results between two organisms, a gold fish and an Elodea plant, to see if both produced cell respiration in a water medium. The results of the test were in support of the hypothesis of both cells going through cellular respiration. Given the results, it can be supported that inside both animal and plant cells, cell respiration is present. Introduction
