Five Stages Of Aerobic Respiration

998 Words4 Pages

Respiration is a series of biochemical pathways that take place in order to create the ATP needed for an organism to survive. ATP is created by either oxidation or reduction reactions depending on what type of respiration process is taking place. An oxidation reaction is when the biochemical pathway has to lose electrons, while in reduction reactions gain electrons to create ATP (Notes, 9/30/15). Aerobic respiration is a biochemical pathways that creates ATP through a series of oxidation reactions. In this type of process, the electron acceptor that would be used is NAD+ and the final electron acceptor has to be oxygen. Oxygen has to be the final electron acceptor since it accepts the electrons that come from the organic compounds eukaryotes …show more content…

In order for aerobic respiration to occur, the 5 stages that have to take place are glycolysis, oxidation of pyruvate, Krebs’s cycle, electron transport chain, and chemiosmosis (Notes, 10/5/15). Glycolysis is the splitting down of the sugar molecules into 2 3-carbon molecules. The reactants for this process are the sugar molecule, 2 ATP, 2NAD+, and 4 ADP+Pi. This is the first stage of this cellular process in which takes place in the cytoplasm and it has to occur in order to generate ATP from the substrate level phosphorylation. The products of this stage are passed down into the next stages. The 2 molecules of pyruvate are passed down to the oxidation of pyruvate, and NADH will be used for the electron transport chain. The rest of the products, 4 ATP, ADP, and P, are used where needed in the cell. After glycolysis occurs, oxidation of pyruvate takes places in the mitochondrial matrix. During this stage, …show more content…

It usually takes place in the leaf and it is used by plants to create sugar from sunlight. Eukaryotic cells within the plant are able to do this type of process by capturing light energy from the sunlight through the use of pigments and converting it into chemical energy. Without the sunlight this process and its stages wouldn’t be able to function properly to create sugar due to it being a light-dependent reaction. Photosynthesis has to take place due to the fact that it helps eukaryotes survive. During this cellular process, oxygen is released in the form of waste in to the atmosphere which is what organisms have to breathe in order to

    In this experiment the rate of cellular respiration was measured by the amount of CO2 in ppm per gram of substance produced by a given treatment group or the control over the course of ten minutes. CO2 levels were measured using a CO2 sensor. The sensor was given time to warm up then placed in a glass chamber with a sample from one of the treatment groups or a sample of control. CO2 levels in ppm were collected every four seconds for ten minutes by the sensor. The data was divided by the weight of the sample used to generate it, to give the respiration rate per gram of sample.

    The ability to carry out metabolic processes, or the chemical activity that occurs in all living organisms, is essential to maintaining life. The total metabolism of an organism is made up of anabolic and catabolic pathways. Anabolic pathways expend energy to build important molecules. On the other hand, catabolic pathways release energy to break down important molecules. The energy found in in these pathways is from respiration.

    Sirtuins (Sir2 proteins) are proteins that exhibit mono-ADP-ribosyltransferase, deacetylase, deacetylase, desuccinylase, demalonylase, demyristoylase, or depalmitoylase activity. They are involved in a broad range of cellular processes which include DNA repair, gene silencing, tumor suppression, life span regulation, apoptosis, inflammation, and stress resistance (low energy/calorie situations). (Michan, 2007) Mammals possess seven cellular regulatory sirtuins (SIRT1-7). SIRT1 partakes in metabolism inflammation in the nucleus and cytoplasm.

    Oxidative Phosphorylation is the metabolic pathway in which mitochondria use their structure, enzymes, and energy released by the oxidation of nutrients to create ATP. If cells become oxygen deficient, the condition known as hypoxia (no oxygen) occurs. This condition can be due to abnormally acidic blood or a lack of critical enzymes necessary for releasing oxygen from red blood cells, so when this oxidative cycle is oxygen deficient, it can’t produce the quantity nor quality of ATP necessary for normal cellular functioning. “Oxygen is alkaline forming in the blood, while carbon dioxide which is produced as a by-product of the oxidation process is acid forming.

    Many organisms use energy to perform their cellular functions. That energy comes from the energy that is stored in food then converted to adenosine triphosphate or ATP. ATP can be obtained with or without oxygen, aerobic respiration and anaerobic respiration. Aerobic respiration produces carbon dioxide (CO2) as a by-product while anaerobic respiration produces Ethanol (C2H6O) or Lactic acid (C3H6O3). In aerobic respiration the “CO2 produced during cellular respiration can combine with water to produce carbonic acid.”

    Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.

    The stomata are the most critical piece to this process, as this is where CO2 enters and can be stored, and where water and O2 exit. Cellular respiration also known as oxidative metabolism is important to convert biochemical energy from nutrients in the cells of living organisms to useful energy known as adenosine triphosphate (ATP). Without cellular respiration living organisms would not be able to sustain life. This process is done by cells exchanging gases within its surroundings to create adenosine triphosphate commonly known as ADT, which is used by the cells as a source of energy. This process is done through numerous reactions; an example is metabolic pathway.

  • Aerobic Respiration Vs Atp Essay

    The human body is a compelling and complex structure that although on the outside looks somewhat simple, has a plethora of behind-the-scenes reactions occurring in a constant cycle. The chemical potential energy stored in adenosine triphosphate (ATP) serves as the body’s energy currency, and is an everyday necessity for basic bodily function (Bergman, 1999). There are several distinct differences between the two types of respiration; aerobic respiration occurs in the presence of oxygen and generates a high yield of ATP, whereas anaerobic respiration occurs in the absence of oxygen and generates a small yield of ATP (Tran & Unden, 1998). The time in which ATP is produced is one of the distinguishing characteristics between the two because it determines the rate at which muscles receive oxygen from the blood, therefore determining the level of endurance of an individual (Weil, 2009).

    Then, tests are performed to determine if the products of aerobic and anaerobic respiration are present in the flasks. The citric acid cycle consists of a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the form of ATP (Biology). The tests detect the presence of carbon dioxide and ethanol. Carbon dioxide should be present irrespective of the type of respiration taking place, but ethanol is present only if fermentation has occurred. Another factor that can indicate whether fermentation occurred or cellular respiration occurred is the amount of glucose utilized during incubation.

    It is never used up in the chemical reaction, however it is recycled and used over and over again. Description Metabolic pathways are controlled by the presence or absence of particular enzymes in the metabolic pathway and also through the regulation of the rate of reaction of key enzymes within the pathway [1]. Each enzyme required for a step in metabolic pathway is a central point of control of the overall metabolic pathway. Without the specific enzyme to catalyze a reaction, the metabolism would be too slow to support life and the pathway cannot be completed [2].
