Respiration is a process through which energy is released from glucose or another organic chemicals. As such, it is significant for the survival of all living organisms, whether animals or plants or microscopic bacteria. It serves two fundamental purposes in living organisms: first is the removal of the electrons generated during catabolism and second, is generation of ATP (adenosine triphosphate). Respiration occurs in two different ways, namely, aerobic and anaerobic. Aerobic respiration is oxygen-based cellular respiration that uses oxygen to generate energies through the breakdown of carbohydrates, fats, and proteins.
During this time, I will be using the aerobic system as I am breathing and I am in the presence of oxygen. While I am using the aerobic system, my body will be producing energy through the three distinct stages that undergo in the presence of oxygen. These are: Glycolysis, the Krebs cycle and the electron transport chain. During these three stages glycogen is converted to Pyruvic acid which is then converted to acetyl- coenzyme A in Glycolysis. Then the Pyruvic acid is placed into a reaction which has produces hydrogen which is then transported to the electron transport chain.
Introduction: Cellular Respiration is a process in which glucose is broken down to produce energy in the form of ATP. One of the products of cellular respiration is carbon dioxide. As cells produce carbon dioxide during cellular respiration, it is carried by the blood cells to the lungs where it is exhaled. To be able to test the rate of carbon dioxide, we use Bromothymol Blue, a chemical indicator that changes color as the pH of a solution changes. In a neutral solution, such as water, Bromothymol Blue is blue in color.
Aerobic respiration is the metabolic process that involves break down of fuel molecules to obtain bio-chemical energy and has oxygen as the terminal electron acceptor. Fuel molecules commonly used by cells in aerobic respiration are glucose, amino acids and fatty acids.. The process of obtaining energy in aerobic respiration can be represented in the following equation: Glucose + Oxygen →Energy + Carbon dioxide + Water The aerobic respiration is a high energy yielding process. During the process of aerobic respiration as many as 38 molecules of ATP are produced
How are these electron carriers reoxidized in anaerobic bacteria? How are these electron carriers reoxidized in aerobic bacteria? 3. (24 points) Aerobic eukaryotic organisms use the unique abilities of mitochondria to extract further energy from glucose (and other nutrients). a) The citric acid cycle completes the degradation of glucose.
Acetyl-CoA is transported within the cell to the mitochondrion, a specialized organelle where acetyl-CoA converts into ATP. Aerobic cellular respiration is a more efficient process producing 38 molecules of ATP compared to the anaerobic process that produces 2 ATP molecules. This sequence of reactions also creates the by-products of water and carbon dioxide (CO2). The by-product carbon dioxide was the compound measured for this experiment. As carbon dioxide is released into the water through the respiration of the crayfish it is converted into carbonic acid shown below.
Both ATP and NADPH are responsible for the reduction of glycerate-3-phosphate into triose phosphate, which is converted into many useful organic compounds like carbohydrates, mainly glucose. Although glucose can be used as a direct energy source by plants, it cannot be used directly by animal cells as a source of energy. Instead, cells use ATP as their immediate source of energy. The conversion
3. Facilitated diffusion - carrier enzymes that are part of the cell membrane permit cells to take in materials that would not diffuse in by them selves. Most cells take in glucose by facilitated diffusion. 4. Active transport - a cell uses ATP to move substances from an area of lesser concentration to an area of greater concentration.
a U turn on a run trail or tight turns around a swim marker). * Lactic Acid System (Anaerobic – without oxygen) Following the exhaustion of the Alactic system fuel is still needed. The anaerobic lactic system is used for medium to high intensity bursts of effort that last between 10 seconds and 2 minutes. Lactic acid is produced as a by-product of anaerobic glycolysis (breakdown of glucose in the absence of oxygen to produce energy). Due to the lactic acid that is produced when using this energy system, athletes will experience a burning sensation in their muscles which accompanies a shortness of breath due to the lack of oxygen in the muscles.
Name : MUHAMAD HANIF BIN KAMAIL Class : M09T Title : ESTIMATING GLUCOSE CONCENTRATION IN SOLUTION Date : 15/10/2009 INTRODUCTION: Glucose (C6H12O6) is a monosaccharide reducing sugar. In this reaction, the glucose readily donates the electrons which are accepted by the permanganate causing it to change colour. The purple pink solution of potassium permanganate (MnO4-) is reduced to a colourless solution of manganese ions (Mn2+). Colourless in solution Purple pink in solution MnO4- + 8H+ + 5e- Mn2+ + 4H2O As a result of this reaction the glucose is oxidised. The time taken for the loss of colour from a standardised solution of permanganate is directly related to the concentration of glucose present in the solution.
