There are two types of respiration: Aerobic (using oxygen) and Anaerobic (no oxygen). Aerobic respiration produces carbon dioxide and water and releases energy. The equation is: C6H12O6 + 6O2 → 6CO2 + 6H20 + Energy ATP A cell cannot get its energy directly from glucose, so during respiration the energy released from the breakdown of glucose is used to make ATP (adenosine triphosphate). ATP is made from the nucleotide base adenine, combined with a ribose sugar and three phosphate groups. It carries energy around the cell to where it’s needed.
Each of these is converted in a number of steps to pyruvate (another 3-carbon sugar), a process that releases some energy, and a hydrogen atom, which is transferred for use in the respiratory chain by the co-enzyme NAD. The Pyruvate molecules then diffuse into the mitochondrial matrices within the cell. They are then converted to acetyl co-enzyme A (a two-carbon compound) with a Carbon Dioxide (CO2) molecule and a Hydrogen atom (taken up by co-enzyme NAD again) given off. Acetyl Co-enzyme A then enters the Krebs cycle. In this metabolic cycle the 2-carbon acetyl compound dissociates from the co-enzyme A and is converted into a 4-carbon oxaloacetate compound, which in turn is converted into a 6-carbon citrate compound.
The enzyme responsible is UDP-Glucose pyrophosphorylase and this reaction consumes UTP. Glucose-1P UDP-Glucose The UDP-Glucose pyrophosphorylase add a UTP to a Glucose -1P to produces UDP-Glucose 4th step: The fourth step consist to transform the UDP-Glucose to Glycogen. This is the last step of the Glycogenesis. The enzymes responsible are Glycogen synthase and branching enzyme.
(Swann, 2008) The pancreas also makes amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and which are converted by other enzymes to glucose to supply the body with energy. Hypothesis: Most enzymes are very specific for a certain substrate. The active site on the enzyme molecule forms a keyhole into which the substrate fits like a key. The substrate molecule is then broken up into many smaller pieces. “The higher the reaction temperature, the more kinetic
Carbohydrate is the universal energy cell. Carbohydrate breakdown, glycogen serves as a source of glucose for your cells, your tissues, including your brain and muscles use glucose as a source of energy to support metabolic functioning. When your body requires glucose your liver and muscle breakdown their glycogen stores releasing glucose. Some glucose may be used directly in your liver and muscles while other glucose is released into your blood stream and used throughout body. Lipid break down, your body can breakdown triglycerides as a source of energy.
Introduction When the oxygen supply runs short in heavy or prolonged exercise, muscles obtain most of their energy from anaerobic process called glycolysis. Yeast cellls obtain energy under anaerobic conditions using a very similar process called alcoholic fermentation. Glycolysis is the chemical breakdown of glucose to lactic acid. This process makes energy available for cell activity in the form of a high-energy phosphate compound known as adenosine triphosphate (ATP). Alcoholic fermentation is identical to glycolysis except for the final step.
The purpose of this practical was to produce a calibration curve, by applying a linear dilution series, to then resolve unknown levels of glucose concentrations. Glucose is a one of the most important carbohydrates used by the human body, it allows us to carry out tasks in the day by providing energy to cells in the body. As our cells respire they produce energy as by product that we need. There are three types of carbohydrates used in the body, these include Monosaccharides being single sugar molecules containing up to seven carbon atoms which cannot be broken down into smaller groups, disaccharides these are formed by linking two monosaccharides and polysaccharides which have the largest molecular weight and are insoluble in water. Glucose is the most common example of monosaccharide (E.Simon, J.Dinkey & J.Reece 2014).
It can be converted into starch, a storage molecule, that can be converted back to glucose when the plant requires it 3. It can be broken down during the process of respiration, releasing energy stored in the glucose molecules In aerobic respiration energy is produced when this reaction happens Oxygen + glucose Carbon dioxide + water + Energy C6H12O6 + 6O2 → 6CO2 + 6H2O + energy The energy released by respiration is used to make large molecules from smaller ones. In plants, for example, sugars, nitrates and other nutrients are converted into amino acids. Amino acids can then join together to make proteins. The energy is also used: * To allow muscles to contract in animals * To maintain a constant body temperature in birds and mammals Respiration and photosynthesis can be linked as the result product can be used as a reactant in the other equation, this means that plants can have a constant supply of energy this means they don’t die in the night.
(10 points) The catabolic cycle called glycolysis is the most universal energy-producing metabolic pathway for organisms that live on or near the earth’s surface. a) Stage I glycolysis actually consumes ATP. In which steps is ATP converted to ADP and how is the phosphate group used? b) Stage II glycolysis produces some ATP directly and also reduced NADH. How are these electron carriers reoxidized in anaerobic bacteria?
It is a polysaccharide that functions as a carbohydrate store and is an important part of the human diet used as an energy source. It is a polymer of glucose sugar which means it is composed of many glucose molecules linked in a chain. Plants store the starch instead of simple sugars. Cellulose is an insoluble substance which is the main part of plant cell walls and vegetable fibres such as cotton. It is also a polysaccharide consisting of chains of glucose monomers.
