Level 3 Applied Science Unit 11 physiology of Human Body Systems Task 1: ORGANELLE DIAGRAM FORM FUNCTION Nucleolus • The nucleolus is a darker staining region of the nucleus. It is non-membrane bound structure composed of ribonucleic acids (RNA) and proteins. It makes ribosomes inside the nucleus and contains all the DNA of the cell.…
The materials and apparatus used in this experiment were: a PC computer, IWX/214, LabScribe Software, SP-304 Spirometer, FH-300 Spirometer flow hear and plastic tubes. The regular set up of the apparatus and more details of the procedure can be found from the Lab Manual on laboratory # 10 respiration, which was used as a reference. After setting the computer software (LabScribe), and calibrating voltage to 22 L which was written in the spirometer black box, a test of the Spirometer was performed to make sure it was in the right position. (A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs.) It was tested by recording one person breath on the software and observed the waves in the lung volume screen.…
Cellular respiration is the process by which cells break down nutrients and produce ATP. The road through cellular respiration can somewhat vary, depending on the nutrient being processed; this article will focus on the pathway of breaking down glucose. There are three main stages of cellular respiration, Glycolysis, Citric Acid Cycle, and the Electron Transport System. For the chemical enthusiasts reading this, the chemical equation to describe cellular respiration is: C6H12O6 + 6O2 ®6CO2 + 6H2O + Energy (ATP and heat). Stage 1:…
Respiration Rate Analysis on Goldfish While Being Exposed to Varying Water Temperatures Avarie Wideman, Bronwyn Edgell, Brooke Farrell, Shannon Porter & Emma Milne 1 Uxbridge Secondary School, Uxbridge, Canada ________________________________________ Results After completing the goldfish respiration experiment we were left with an abundance of data that has lead us to these results. Through the experiment we have discovered that the goldfish's respiration is affected when exposed to extreme water temperatures compared to the controlled temperature. Such as in Table 1, one can see this difference between the hot temperature (30 °C) in comparison to the cold temperature (18°C). This is the most dramatic variables of the experiment during respiration, it is evidence that the temperatures can affect the rate significantly.…
When analyzing the given graph showing the relationship between anaerobic respiration and temperature, it can be seen that at -20° C the amount of fermentation during anaerobic respiration is zero, as the temperature increases the amount of fermentation increases, until 35°C when fermentation is at 100%. Interestingly, as the temperature increases further, fermentation decreases until at 60°C it ceases once more. At Earth’s beginning it is thought that the earth was covered with active volcanoes and was very hot, consequently it would have been too hot for anaerobic respiration. Once the earth’s atmosphere had cooled to below 60°C (140°F) then I assume that anaerobic respiration would have gradually increased as there was thought to be little…
From the table of result, the highest percentage of killed bacteria is 99.7% with only 4 live colonies in the tube 1. It proven that vinegar is a great disinfectant as there is a huge number of killed bacteria. This is because there is 100% of disinfectant. Inversely, tube 4 has the lowest percentage of killed bacteria, where only 37.5% of bacteria are killed. Tube 4 has a huge number of live colonies with 580 colonies.…
In this experiment, the experimenters were testing how aerobic respiration was effected by a change of temperature for germinated and ungerminated garden peas (Pisum sativum). In this experiment, 30 germinated P. sativum were gathered and their seedcoat was removed. The seeds were then soaked in water at the temperatures on 10ºC, 20ºC, 30ºC, 40ºC and 45ºC for five minutes. After the five minutes pass, the water was drained from the pees and put into a cooled, 10ºC, test tube and an oxygen sensor was insert into the top of the tube. Once the oxygen sensor sat in the tube for five minute, the results were then recorded and the steps were repeated for the next four temperatures.…
Cellular respiration is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products (Wikipedia, n.d.). Metabolism affects the processing of a pear as it moved through the process of cellular respiration. Furthermore, there are three steps in the cellular respiration process. The three-stage process consists of glycolysis, the Krebs Cycle, and the electron transport chain, and the purpose of the process is to convert glucose and oxygen to ATP and to release carbon dioxide and water (Wikipedia, n.d.).…
Throughout his text On The Use of Breathing Galen identifies the purposes of respiration by examining his predecessors’ various theories on the matter and proving which of these theories must hold true. He spends a lot of time disproving Erasistratus’s theories of respiration as a means to replenish arteries and appears to believe that Hippocrates’ ideas on respiration respiration for the purposes of both cooling and nourishment. Though not mentioned by name, Galen’s views on respiration appear to match up on key points with Aristotle’s views on respiration, as outlined in his text On Respiration. Galen first and foremost addresses the issue of whether respiration acts as a cooling agent within the body.…
Scientific Paper Introduction The smallest unit of life is the cell. Cells make up tissues, tissues make up organs and organs make up organ system which make up organisms. Organisms are made up of millions of cells and these cells pretty much run all function of the body. But to function and live these cells need to acquired energy and they do it through chemical reactions called cellular respiration, if it is an animal cell, or photosynthesis, if it is a…
The result of this experiment was that tube 5 and 6 decreased in mass. Tube 2, 3 and 4 increased in mass. This is because in the hypertonic solution, water in the tube was flowing outwards, because the concentration of dissolved solutes was greater outside the tube than inside it. This caused the tube to shrink, for example, beaker number 5 and 6 with 40 % sucrose outside and 20% inside the tube. Apart from this, in hypotonic solution, water was rushed into the tube by osmosis, which is not good for the cell because it will fill with water and burst, for…
Determining The Process of Photosynthesis And Cellular Respiration Using Elodea and Yeast Introduction Photosynthesis is an essential process to life on earth, in which plants and other organisms use sunlight to create food from oxygen, and carbon dioxide. Cellular respiration is when energy in food is released and converted to ATP, which is then used as chemical energy to complete tasks within a cell. This process usually requires oxygen and releases carbon dioxide. Photosynthesis and cellular respiration are similar in some areas and different in others. The purpose of both of the process is to produce energy, but they have different ways of achieving this goal.…
It requires energy. 5. Cells would use too much energy just for transporting molecules. This might cause the organism/animal to spend most of its time taking in energy by eating. Cells would require vast amounts of energy to perform even simple functions.…
Organisms are composed of countless eukaryotic cells each with a set niche to make sure the body stays balanced. Form their inception cells are programmed like a computer to provide necessary functions for a person’s body. Along the lines of being like a computer all cells need power to operate. Inside the cell its organelles help the cell attain the fuel it needs to operate. Within these group of organelles is what has been aptly named the, “power plant”, of cells for it takes nutrients and converts it into fuel for cells.…
The hypothesis that rate of respiration of chickpeas is highest at room temperature is not supported by the data, although there was error in the data. The data from the lab showed rate of oxygen consumed to be the highest at 1.5 degrees Celsius with a rate of .0124ppt/min/g. At room temperature there was a rate of .0077ppt/min/g, and at the hottest temperature (95.6 degrees Celsius) a rate of -.0131ppt/min/g, meaning that oxygen was not consumed but actually increased in concentration in the biochamber. In reality, room temperature should have had the highest consumption of oxygen, the cold temperature should have a less amount of oxygen consumption, and the hot temperature should have had no oxygen consumption, and should have stayed at…
