Cellular Respiration Lab Report

Cellular respiration is a process that takes place in the cells of organisms to convert biochemical energy from the energy stored in bonds of molecules. To convert this energy the cells take nutrients into adenosine triphosphate, also known as ATP then release the waste products to complete the process. The process of cellular respiration is constantly performing due to the immediate consumption of ATP. In order for cell respiration to take place, there are going to be multiple enzymes involved, composed of cofactors (usually inorganic ions such as magnesium) or coenzymes (usually organic molecules). These enzymes are essential to bind its substrates to its active site and either forming or breaking chemical bonds. They function to speed up

Glucose being a monosaccharide is the most effective fuel for cellular respiration producing a great deal of ATP. Maltose is formed by amylase breaking down starches. It is a type of carbohydrate that is necessary for the body to properly function. Being a disaccharide of glucose, the bond holds two monosaccharaides together forming a glycosidic bond. It is often found in developing cereal grain seeds. (3rd.Smith D., Jurukovski V.) Another food source would be alanine, which is an amino acid, which is the fundamental of most proteins. It is most common when the transfer of an amine group creates pyruvate. This can be done by the reactions being readily reversible. Alanine can be easily formed from pyruvate and has close links to metabolic pathways such as glycolysis and the citric acid cycle. Alanine can play a role in substrate recognition, particularly in interactions with other non-reactive atoms such as Carbon. It can be found in any protein food such as meat, fish, eggs and dairy products. The goal of the following experiment is to verify conditions and their effects on cellular respiration by measuring the CO2 production. The results should confirm that the most efficient fuel for cellular respiration in yeast fermentation (saccharomyces cerevisiae) would be glucose, followed by maltose and alanine. An addition of excess amounts of Mg++ will result

The most gas was produced in the presence of glucose because it is a bi product of fermentation of the yeast, the gas in the tubes represented the CO2 of a result of fermentation. More Mg increased the cellular respiration because it released more CO2. The NaF decreased in CO2 because it was an inhibitor to the enzyme. Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The more CO2 released the more ATP produced. If they’re “happy” they make more CO2 bubbles. The process occurs in two phases, glycolysis which is the breakdown of glucose to pyruvic acid and then the complete oxidation of pyruvic acid to CO2 and water. It is the release of energy from organic compounds by chemical oxidation that happens in the mitochondria within each cell. (Saladin,(2007)). The lab demonstrated that although there are many important things relating to cellular respiration. It showed the rates of cellular respiration was greater with the combination of yeast, water and glucose resulting in the most efficient fuel source. It also showed the temperature was directly proportional, as temperature increases, respiration rates would have increased, that’s why the tubes were placed in a bath of the same temperature, being body temperature, 37°C for the same amount of
