Transcript of The Breakdown of Glucose in a Cell

Breakdown Of Glucose Virtual Journey of
Cellular Respiration Other Facts Where Do the Products Go? What is This Process Called? Where Do the Reactants
Come From? What are the Products? What is Needed? The cells that are in organisms breakdown glucose and transfer energy into ATP (Adenosine triphosphate). C6H12O6 (Glucose) + O2 (Oxygen): Glucose and Oxygen are needed to perform the process of breaking down the glucose in our cells, called Cellular Respiration. The products of Cellular Respiration are: CO2 (Carbon Dioxide), H2O (Water), and Energy (in the form of ATP and Light). These products come from the breaking down of the Glucose and Oxygen molecules during the process of Cellular Respiration. The glucose reactant comes from the sugars in food being broken down in cells within the organism. The oxygen comes from the air we (the homogeneous species AKA "animals") take into our lungs. Each product is released in different ways and are released into different places. The CO2 (Carbon Dioxide) product is released into the air by exhalation. The H2O (Water) product is stored in out cells and is also released in our human waste products. The energy product is released into the atmosphere in the form of heat(unexplained scientifically as to why 90% of our energy is lost in the form of heat). This process is commonly known as Cellular Respiration. This process takes place within the mitochondria that is found in our cells. Cellular Respiration has two other processes within the main process itself; The Krebs Cycle and Glycolosis. ATP (Adenosine triphosphate) is the energy for cellular activity This process also includes making and sorting energy for the electron transport train within our cell membranes. This process, which includes the process of Glycolosis, produces ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate). It produces 36 ATP molecules. NADPH (nicotinamide adenine dinucleotide phosphate oxidase) and NADP+(nicotinamide adenine dinucleotide phosphate; this is the greater version of NADPH)are produced as well during Cellular Respiration. Glycolosis and the Krebs Cycle Glycolosis is the process in which one glucose molecule is broken down into 2 pyruvic acid. This process occurs in the cytoplasm of plant, animal, and microorganism cells. The Krebs Cycle is the process that uses the 2 pyruvic acids molecules that were formed during Glycolosis. This happens in the moitochondrion of a cell; the part of the cell that produces the ATP. Some Other Little Facts The chemical formula of Cellular Respiration is shown
as the following:
C6H12O6 + O2 --> 6H2O + 6CO2 + Energy
