How does the mitochondrion make ATP? Glycolysis breaks down a glucose molecule Pyruvate is created via Glycolysis The acetyl CoA is produced from Pyruvate Citric acid comes from acetyl CoA and Oxaloacetate Citric acid was the starting molecule for the Krebs cycle The NADH and the FADH2 were generated by the Krebs cycle Oxidative Phosphorylation involves electron transport chain (ETC) and Chemiosmosis The electron transport chain pulled electrons off of NADH and FADH2 The protons

* * Cellular respiration is the multi-step process in which oxygen is transformed within cells * producing carbon dioxide‚ the process purpose is transforming fuel intake into energy for cells. The three stages are glycolysis‚ citric acid cycle‚ and oxidative phosphorylation. (Dickey‚ Reese‚ Simon‚ 2010). * * What is the role of glycolysis? Include the reactants and the products. Where does it occur? * * Glucose‚ the body’s fuel is utilized in the role of glycolysis

Biochemistry GRT 1 Task 4 -Case Studies Marie Marks Western Governors University Introduction The two case studies given both involve in the processes of making energy that the body needs to maintain and sustain life. Each case is a different diagnosis but they both have some involvement in the production of ATP and other products when creating energy. If someone has an issue with the production of energy it is hard to maintain life in the body. The body has many different enzymes that are

1 Western Governors University 2 Hereditary Fructose Intolerance Metabolism is the process of cellular respiration. It involves three steps‚ 1) glycolysis‚ 2) the citric acid or Krebs cycle and 3) electron transport system. The glycolytic pathway or glycolysis is a metabolic process that leads to the formation of the energy source adenosine triphosphate (ATP) in the body. ATP is essential to the cell and the cellular processes used by the cell. The first step‚ glycolysis is the process

lactic acid C3 O6 H3 and energy as follows: C5 H12 O6 2C3 H6 O3 + energy Anaerobic respiration is a stage of cellular respiration that happens in the absence of oxygen. The first step is the breakdown of glucose in glycolysis. During this step glucose is broken down to two pyruvic acid molecules. The fate of pyruvic acid depends on whether there is oxygen available or not. In the absence of oxygen‚ pyruvic acid continues the anaerobic respiration pathway and is converted into lactic acid. Only

intercellular reactions in which energy-rich molecules are broken down to form ATP‚ using O2 and producing CO2 (2). In most cells‚ ATP is generated from the disassembling of absorbed nutrient molecules in three stages‚ glycolysis: in the cytosol‚ the citric acid cycle: in the mitochondrial matrix and oxidative phosphorylation: at the mitochondrial inner membrane (1). The 6-carbon molecule of Glucose is broken down into 3-carbon pyruvate molecules during the nine stages of glycolysis. However‚ for this reaction

two closely parallel pathways‚ where if both Glycolysis and Gluconeogenesis happen at the same exact moment‚ ‚ the net result would be the hydrolysis of four nucleotide triphosphates (two ATP plus two GTP) per reaction cycle. However‚ this non reciprocal regulation is a futile cycle‚ which would simply waste ATP if allowed to run freely. In reciprocal regulation‚ the amounts and activities of the distinctive enzymes of each pathway are

When a muscle is stimulated to contract aerobically‚ less lactic acid is formed than when it contracts anaerobically because: a) b) c) d) glycolysis does not occur to significant extent under aerobic conditions. muscle is metabolically less active under aerobic than anaerobic conditions. the lactic acid generated is rapidly incorporated into lipids under aerobic conditions. under aerobic conditions in muscle‚ the major energy-yielding

Ethanol (Alcohol) is a toxin that is quite commonly and regularly consumed by individuals‚ yet it contains a lot of potential energy when converted to Acetyl CoA. This is an essential component of the Kreb’s (citric acid) cycle and the synthesis of ATP. Alcohol is an open-chain (aliphatic) compound‚ and dissolves easily in water
