In contrast, there are four metabolic stages happened in cellular respiration, which are the glycolysis, the citric acid cycle, and the oxidative phosphorylation. Glycolysis occurs in the cytoplasm, in which catabolism is begun by breaking down glucose into two molecules of pyruvate. Two molecules of ATP are produced too. Some of they either enter the citric acid cycle (Krebs cycle) or the electron transport chain, or go into lactic acid cycle if there is not enough oxygen, which produces lactic acid. The citric acid cycle occurs in the mitochondrial matrix, which completes the breakdown of glucose by oxidizing a derivative of pyruvate into carbon dioxide. The citric acid cycle produced some more ATPs and other molecules called NADPH and FADPH. After this, electrons are passed to the electron transport chain through

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 involves glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis is a

Cellular respiration is a very important process that occurs in all living organisms. In this process, chemical energy is obtained by the organisms’ food source to be turned into ATP or adenosine triphosphate, a form of energy that is easily utilized by the organisms’ bodies to carry out certain bodily functions (Largen, 2008, p.41). The chemical formula for cellular respiration is C6H12O6+6O2+6H2O→6CO2+12H2O+energy. This simply means that, with the use of glucose, six molecules of oxygen, and six molecules of water, an output of six carbon dioxide molecules, twelve molecules of water, and energy (ATP) is produced (Khan, 2010). Glucose is especially important in this process, given that it acts as a fuel in cellular respiration. (Cellular Respiration: Introduction, n.d.). In the biosphere, there is also a vast

All cells in the human body require sufficient amount of energy in order to sustain life. Cells get their energy through a process called cellular respiration. In this process cells use glucose in the presence of oxygen as a fuel source to synthesize highly energetic molecules of adenosine triphosphate (ATP). ATP is immediately consumed after its formation, so the process of cellular respiration is constantly ongoing. The starting components, glucose and oxygen are converted into carbon dioxide, water and energy. The process of cellular respiration can be divided into three stages: glycolysis, Krebs cycle (citric acid cycle), and the electron transport chain. At the end of the process a total of 38 ATP molecules are produced. In this experiment,

Chapter 4 of our textbook (OpenStax College, 2013, p. 116) explained the processes of aerobic and anaerobic cellular respiration. Aerobic respiration uses oxygen as the final electron receptor, whereas anaerobic respiration uses an inorganic molecule to complete the process. In addition, Chapter 4 (OpenStax College, 2013, p. 114) also illustrated the molecular breakdown involved in lactic acid fermentation. This process occurs when skeletal muscles have reached the point of fatigue and lack oxygen. Chapter 2 (OpenStax College, 2013, p. 45) introduced ATP and its importance of providing energy to cells in living organisms.

This experiment employs the concept of cellular respiration. Cellular respiration is the release of chemical energy from sugars and other carbon molecules to produce ATP, which is the energy source for cells. Respiration occurs in all eukaryotic cells, inside the mitochondria. ATP is made from glucose molecules that are eaten in food, and the process has a byproduct of carbon dioxide. The balanced chemical equation is: C6H12O6+6O2=6CO2+6H2O. Simply put, it is a sugar and oxygen that yield carbon dioxide and water.

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

Upon reaching the cell, both oxygen and glucose interact to perform cellular respiration. There are two phases, the first known as glycolysis. Glucose is a six-carbon sugar which is broken down into two molecules of 3-carbon molecules known as pyruvate. Then the second phases, known as the Kreb Cycle (Citric Acid Cycle) occurs inside the mitochondria and generates a pool of energy (ATP, NADH, and FADH2). The pyruvate is transported into the mitochondria and loses carbon dioxide to form acetyl-CoA, a molecule that contains two

Cellular respiration is defined as the process by which the chemical energy of food molecules is released and converted into usable energy in the form of adenosine triphosphate (ATP). (Encyclopaedia Britannica Online, 2015) Excluding viruses, all living organisms respire. (kids.net.au, 2015) There are two types of respiration; aerobic and anaerobic. Aerobic respiration occurs in the presence of oxygen. Anaerobic respiration occurs when there is an absence of oxygen. (kids.net.au, 2015) Cellular respiration occurs in three main stages: glycolysis, Krebs cycle and the Electron Transfer Chain. (Encyclopaedia Britannica Online, 2015) Glycolysis is the anaerobic process of breaking down glucose into what is known as pyruvate. Pyruvate can be broken down further in The Krebs cycle, which is an aerobic process where glucose is converted to ATP.

There are three processes that all take part in Respiration, and they are all very similar. They are Glycolysis, the Krebs Cycle, and the Electron Transport Chain. These three processes help make up what we know as Cellular Respiration. Glycolysis is broken down into two parts: Investment and Harvest. In Harvest there is something called Glucose. The glucose, C6H12O6, combines with another related system called Fructose. Together these two make another process call Glyceraldehyde. In this process, Glyceraldehyde, G3P which has 3 phosphate, gets carried over to the second part of the Glycolysis processes called the Harvest. In Harvest, this is where the NADHs come into play and get somewhat discombobulated. The NADHs help carry over energy and create ATP and ADP. The NADH then loses its H and then distributes it to become 2 NAD. This cycle is only one of three in the Cellular Respiration process.

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).

Adenosine triphosphate (ATP) is an important organic molecule in all living organisms, it is a biologist fuel for all living organisms.(Vanputte et al. 2014) When the energy stored in ATP is used, ATP will be broken down to adenosine triphosphate and inorganic phosphorous (Astrand 1956). Cell Respiration is the way that the human body produces more ATP, and there are four parts in total which is glycolysis, Link Reaction, Krebs cycle and Electron Transport Chain respectively. However, if when oxygen is not present in the cell, then the private undergoes alcoholic fermentation and lactate formatted in the process of anaerobic respiration (Peeters Weem et al. 2007).

The Krebs cycle also known as the Citric Acid cycle, is the second part of the three steps in which cellular respiration happens. The Krebs cycle was discovered and named after Hans Krebs, a German scientist. The Krebs cycle takes place in the mitochondrial matrix of the cell, occurring between glycolysis, which breaks down glucose turning into pyruvate, and oxidative phosphorylation, which is what creates ATP. This is processes where the body harvests energy from the food we consume. The Krebs cycle takes in the energy stored in the bonds of acetyl CoA. The energy taken in from the Krebs cycle is then passed on to oxidative phosphorylation, where it is transformed to a usable form of cellular energy, ATP. We then use that energy to move, breathe, for our hearts to beat, along with many other functions. The Electron transport chain is the third step in the process of cellular respiration, after the Krebs cycle. “The main purpose of the electron transport chain is to build up a surplus of hydrogen ions (protons) in the intermembrane space so that there will be a concentration gradient compared to the matrix of the mitochondria.”(Quia, N.D) The electron transport chain is made up of four protein complexes located in the inner mitochondrial membrane.

The citric acid cycle (CAC), also known as the Krebs cycle and the tricarboxylic acid cycle, is a stage of cellular respiration. The role of the cycle is to oxidise fuel molecules and to provide precursors in the form of carbon skeletons for other metabolic pathways (e.g. fatty acid synthesis, amino acid synthesis etc.). The CAC is described as amphibolic, as it has both catabolic and anabolic functions. Catabolism is the breaking down of substances to provide chemically available energy (e.g. ATP) and/or to generate intermediates used in anabolic reactions, whereas anabolism involves the formation of complex molecules from simpler ones and the storage of energy. The cycle can be regulated to either increase or decrease the rate of reaction, and regulation is often carried out via allosteric inhibition of CAC enzymes.
