Review Questions Write one-paragraph responses to 4 of the following 6 questions below. Each paragraph should be 5 to 10 sentences (or about 70 – 150 words), and written in your own words. Session 1: Cell Pathology 3. Cell injury can be reversible or irreversible, and hypoxia is a major cause. Explain how hypoxia causes reversible cell injury (in particular hydropic change), which can then lead to cell death.…
The primary function of red blood cells is to transport respiratory gases, such as O2 and carbon dioxide (CO2), to the body’s tissues and organs. Each RBC contains hemoglobin which has the capacity to carry four O2 molecules. Therefore, if the amount of blood supplied to an organ is reduced, the amount of O2 that is delivered to that organ is reduced as well (Hoehn & Marieb, 2010,…
My group was assigned with seeds that have been germinated for 72 hours. The purpose of this experiment was to study cellular respiration in germinating peas at room temperature versus non-germinating peas at room temperature, versus germinating peas cold, by measuring and comparing their consumption of O2 and CO2. We compared the cellular respiration rate of germinating and non-germinating peas. Additionally, we observed how temperature affects cellular respiration by manipulating the temperatures of the water bath, and comparing the cellular respiration rate between the germinated peas at room temperature and the germinated peas in the cold water…
This is the process that organic compounds will be degraded from oxygen to produce water, carbon dioxides, and different forms of energy such as ATP (Reece, et al. 2014). Cellular respiration is important to life because breaking down sugars into usable energy enables living organisms to function to support their life. This topic relates to our lab experiment because…
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…
Rafaela Hajdini Bio 104- 55 November 11th 2014 Fermentation Lab Report Abstract: Introduction: Cellular respiration is a reaction that the majority of living organisms partake in to get adenosine triphosphate (ATP), by obtaining chemical energy, to synthesize in three different phases; glycolysis, citric acid cycle, and the electron transport chain. Both glycolysis and the citric acid cycle are anaerobic pathways which means that oxygen is not need to form energy.…
(a) Acidosis is a result of reduced pH levels in the blood. A person stops breathing during cardiac arrest because, as the heart stops pumping blood, there is no pulmonary circulation. As a result, the lungs are not removing CO2 produced by the body. Excess CO2 causes the pH of blood and other bodily fluids to decrease, making them too acidic. In other words, acute respiratory acidosis occurs because the person cannot breathe during cardiac arrest.…
My photosynthesis project is gonna be about how photosynthesis and cellular respiration how they are different and alike in many different ways we are creating a poster on photosynthesis and cellular respiration. photosynthesis does its own thing just like a cellular respiration does its own thing. cellular respiration and photosynthesis are both independent. cellular respiration and photosynthesis have a process to keep the energy flowing.. photosynthesis is a process that captures energy from sunlight that stores chemical energy.sunlight has several types of radiant energy such as ultraviolet radiation.plants absorb visible light for photosynthesis.light energy is converted to chemical energy by chlorophyll.photosynthesis is is affected…

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.…
This is where cellular respiration - the conversion of glucose into energy - takes place. The mitochondria’s role is to take in the glucose from food and convert it into energy, also known as ATP in a process called Oxidative Phosphorylation. The mitochondria contain an inner and outer membrane, Oxidative Phosphorylation occurs in the inner membrane which has folds that help it create more ATP. This energy is used for cellular…
The main jobs are, regulate our nerve and muscle function, regulate our body's hydration, blood pH, blood pressure, and the rebuilding of damaged tissue. Sodium and Potassium are the most important because you lose them faster after an intense workout. Sodium is most often found outside the cell in the plasma of the body’s bloodstream. It is a significant part of the amount of water in the body. If there is too much sodium in a person's body it is removed by kidney and water follows.…
INTRODUCTION Cellular respiration is the breaking down of organic molecules by means of catabolic pathways that uses electron transport chain to produce ATP (Campbell 2011). ATP is used as energy in the synthesis of light or also known as Photosynthesis . ATP is used by photosynthetic organisms to produce their own food and also by performing cellular respiration. It needs mainly glucose and oxygen that involves the transfer of electrons in a chemical reaction.…
Carbohydrates are not bad for you, all you need to do is make sure you are eating the RIGHT carbohydrates and you will feel better, reduce the risk of disease and lose weight. It's all a question of eating the RIGHT carbohydrates; let's see the difference and the importance of carbohydrates for normal body functions. Carbohydrates are not all bad just as all fats and some proteins are healthier than others. Carbohydrates what they do Carbohydrates are the primary fuel source for many of the body's vital organs, including the brain, central nervous system, kidneys and heart.…
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…
