Raw Materials from Food Synthesis to Make Energy for Animals

Cellular respiration is the process by which cells get their energy in the form of ATP. There are two types of cellular respiration, aerobic and anaerobic. Aerobic respiration is more efficient and can be used in the presence of oxygen. Aerobic respiration, or cell respiration using oxygen, uses the end product of glycolysis in the TCA cycle to produce more energy currency in the form of ATP than can be obtained from an anaerobic pathway.

Cellular respiration is the chemical process in which organic molecules, such as sugars, are broken down in the cell to produce utilizable energy in the form of ATP. ATP is the chemical used by all of the energy-consuming metabolic activities of the cell. In order to extract energy from these organic molecules, cellular respiration involves a network of metabolic pathways dedicated to this task.

To be able to carry on metabolic processes in the cell, cells need energy. The cells can obtain their energy in different ways but the most efficient way of harvesting stored food in the cell is through cellular respiration. Cellular respiration is a catabolic pathway, which breaks down large molecules to smaller molecules, produces an energy rich molecule known as ATP (Adenosine Triphosphate) and a waste product that is released as CO2.

In cellular respiration, the oxidation of glucose is carried out in a controlled series of reactions. At each step or reaction in the sequence, a small amount of the total energy is released. Some of this energy is lost as heat. The rest is converted to other forms that can be used by the cell to drive or fuel coupled endergonic reactions or to make ATP.

In cellular respiration, glucose and oxygen are taken into the cells, then they are converted to carbon dioxide, water and ATP energy and some other energy. Some of the ATP energy is used in photosynthesis; a large amount of

One of the most significant reactions in Glycolysis is reaction one which involves the phosphorylation of glucose to form glucose-6-phosphate. Through the transfer of the hydrolysis of ATP, this supplies energy for the reaction and makes it essentially irreversible, having a negative free energy change, which allows for a spontaneous reaction in cells. Although the preparatory phase is energy consuming and uses up 2 ATP, the pay off phase synthesizes 4 molecules of ATP, with the transfer of 4e- via 2 hydride ions to 2 molecules of NAD+. Therefore, a net gain of 2 ATP is achieved through the glycolytic pathway alone. Following the glycolytic pathway, due to the absence of oxygen, as oxygen cannot be supplied fast enough to undergo aerobic respiration, the athlete will instead, undergo lactic acid fermentation. Lactic acid fermentation involves pyruvate that is formed from the glycolytic pathway to be reduced to lactate, with the aid of the enzyme, lactate dehydrogenase, while the coenzyme Nicotinamide Adenine Dinucleotide (NADH) is oxidised to NAD+. The product NAD+ then re-enters the glycolytic pathway in order to produce 2 ATP. This process of lactic acid fermentation produces 2 ATP for each cycle, and thus, rapidly supplies the body with a small amount of energy. However, with the buildup of lactic acid in the body, the athlete will eventually encounter the feeling of discomfort as this accumulation of lactate causes the body to

Uniquely, glycolysis is both anaerobic and aerobic. The end product pyruvate, from glycolysis, is anabolized to lactic acid when there is a need for energy without an adequate supply of oxygen available. This last step or reaction enables glycolysis to continue producing ATP without the need for oxygen, which is why it is called the anaerobic energy system (Fink, 2009).

Also, unlike photosynthesis, cellular respiration is known as a decomposition reaction. During this reaction, the exergonic release of energy is produced by breaking glucose down into smaller ATP molecules, water and carbon dioxide which is released into the air, for use by plants, every time we exhale

Introduction: Cellular respiration and fermentation are used in cells to generate ATP. All cells in a living organism require energy or ATP to perform cellular tasks (Urry, Lisa A., et al. , pg. 162). Since energy can not be created (The first law of thermodynamics) just transformed, the cell must get its energy from an outside source (Urry, Lisa A., et al. , pg.162). “Totality of an organism’s chemical reactions is called metabolism” (Urry, Lisa A., et al., pg. 142). Cells get this energy through metabolic pathways, or metabolism. As it says in Campbell biology, “Metabolic pathways that release stored energy by breaking down complex molecules are called catabolic pathways” (Urry, Lisa A., et al. pg.

    Cellular respiration is the group metabolic reactions that happen in the cell of living organism that creates adenosine triphosphate, ATP, from biochemical energy. The formula for cellular respiration is C6H12O6 +6O26CO2+6H2O+ATP.  This formula means glucose and oxygen are turned into water,carbon dioxide and adenosine triphosphate (ATP) energy through chemical reactions. Cellular respiration occurs in all cells which allows them to grow. Raphanus raphanistrum subsp. Sativus seed, also known as radish seed, undergo cellular respiration because they are not yet able to perform photosynthesis, which is how plants create their energy. Hymenoptera formicidae,commonly known as ants, undergo cellular respiration to produce the energy they need to live.

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 two carbon molecule bonds four carbon molecule called oxaloacete forming a carbon molecule knew as citrate. The second step reaction is classified as oxidation/reductions reactions. This process is formed by two molecule of CO2 and one molecule of ATP. The cycle electrons reduce NAD and FAD, which join the H+ ions to form NADH and FADH2, this result to an extra NADH being formed during the transition. In the mitochondrion, four molecules of NADH and one molecule of FADH2 are produced for each molecule of pyruvate, two molecules of pyruyate enter the matrix for each molecule of oxidized glucose, as a result of these eight molecules of NADH+ two molecules are produced. Six molecules of NADH+, molecules of FADH2 and two molecules of ATP synthesize itself in Krebs cycle. As a result, no oxygen is used in the described reactions. During chimiosmosis, oxygen only plays a role in oxidative phosphorylation. The next step is the electron transport; the electrons are stored on NADH and FADH2 and are used to produce ATP. Electron transport chain is essential to make most ATP produced in cellular respiration. The NADH and FAD2 from the Krebs cycle drop their electrons at the beginning of the transport chain. When the electrons move along the electron transport chain, it gives power to pump the hydrogen along the membrane from the matrix into the intermediate space. This process forms a gradient concentration forcing the hydrogen through ATP syntheses attaching

Every living thing needs cellular respiration to survive. Cellular respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. This process happens through three distinct operations which are glycolysis, the Krebs cycle, and the electron transport chain. Throughout these cycles, our bodies turn oxygen and glucose into carbon dioxide, water, and energy. Although this system seems simple enough, cellular respiration can not take place in just one step because all of the energy from glucose would be released at once, most of it being lost in the form of light and heat. All this plays a very important role in our lives and without it, organisms would cease to exist.

Cellular respiration is a process that happens in all living eukaryotic cells. What cellular respiration does is turn food often carbohydrates into energy for our bodies. Cellular respiration starts with a carbohydrates sugar called glucose. What it does is alter and break down the six carbon molecule glucose and altering it creating two three carbon molecules called pyruvic acids in an anaerobic process called glycolosis (Cellular respiration). What this process does is create two ATP molecules which are basically molecules which provide energy to run all cellular processes in our bodies (king). However, from here in the process can turn aerobic, meaning using oxygen if present or anaerobic meaning when oxygen is not present in a
