Are there any differences in the rate of metabolism of a dried yeast culture with differing carbohydrate sources? In the current practical that was undertaken the growth rate of yeast (S. cerevisiae) with differing carbohydrates sources : Glucose (C6H12O6)‚ Fructose (C6H12O6)‚ Lactose (C12H22O11)‚ Xylitol “(CHOH)3(CH2OH)2” and Water (H2O) as a Control were observed. “ Yeast are single-celled fungi which consist of more than one thousand different species which have been identified. The most commonly

For the preparation of the filtrate solution at the beginning of the class our Instructor‚ Marshall Douglas added about four to five strawberries in the blender along with 100 ml of detergent/ enzyme/ salt solution. They were blended until thoroughly homogenized if foaming occurred more detergent solution was added to prevent it. Then the blended solution was poured into a beaker and left to incubate at 60C for 15 minutes. Also‚ the mixture solution was cooled on ice for 5 minutes and filter through

It was hypothesized that if the animal was larger‚ then it would have larger hemoglobin. It was thought that larger mammals would need more oxygen-rich hemoglobin to support healthy function. This lab did not support this hypothesis. The results in table 1 displayed that the hemoglobin of all mammalian samples traveled about the same distance. This trend can be seen in graph 1 as the mammalian hemoglobin samples migrated the same distance. Because the proteins traveled around the same distance it

oxidative metabolism and cellular responses to bacterial invasion‚ xenobiotic and cytokines. To counteract the formation of ROS‚ a number of antioxidant proteins have been described. These proteins are superoxide dismutase‚ catalase‚ glutathione peroxidase‚ glutathione S-transferase‚ and ferritin heavy chain etc. Oxidative stress has been implicated to both the onset and progression of type I and type II diabetes ( ). The consequence of ROS production is associated with the development of

Physics Lab Report Format General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a “one size fits all”‚ therefore this sample lab report should only be used as an example. Any lab report should have the following features:

These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be

structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic proteins;
