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

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

Governor’s University GRT1 Metabolism Enzymes are molecules that are responsible for chemical reactions that occur within the body. They act as catalyst by accelerating metabolic reactions from the digestion of foods to synthesizing deoxyribonucleic acid (DNA). An enzymatic reaction changes substrates‚ the beginning molecule‚ into products. Enzymes are selective for the type of substrate that they will bind to; they have specific shapes that fit into one another like a lock and key as illustrated in

” (Haldeman-Englert‚ 2011) A4. Substrate The specific substrate acted on by Aldolase B is fructose-1-phosphate (F1P). This then is converted into DHAP and glyceraldehyde. Once the conversion is finished the product can enter the glycolysis cycle to from ATP or energy used for the body. “In normal cellular conditions‚ the primary enzymatic activity of aldolase B is to cleave fructose diphosphate (FDP).” (Roth‚ 2012) A5. Role of Aldolase B Aldolase B is the substance needed to breakdown
Premium Adenosine triphosphate Cellular respiration Glycolysis
Adenosine Triphosphate Enzymes are proteins and their function is to act as catalysts to speed up certain chemical reactions in the cell that would be slower without them. This process occurs as steps in a cycle with separate reactions in each step. If there is a missing product the step in the cycle will be incomplete and the normal function of the organism cannot be accomplished causing negative effects on the organism. The biological processed of the body would occur much more slowly or possibly

* * 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

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
