Effect of Temperature on Enzymes ~Abstract~ In this experiment the effect of different types of temperatures on enzyme activity was examined. The temperature baths that were used to test the difference in enzyme activity on fresh liver were; 4 °C‚ room temperature which was 22°C‚ body temperature which is 37°C‚ and 77°C. The total time of each trial was 2 and a half minute‚ 1 minute for the H2O2 to acclimatize to the temperature‚ 1 and a half minutes for the reaction to occur. Catalase causes Hydrogen

Biological Basis of Love The aim of this essay is to discuss and evaluate a more recent area of neuropsychology‚ which is the biological basis of attraction. The focus of the essay will be on how certain brain activities in regions of the brain are associated with feelings of attraction in an individual. These forms of attractions can be seen as types of love towards a potential mate and this essay will be targeted at defining what love is and the type of loves there are. The essay will then link

Enzymes are biological molecules (proteins) that act as a catalyst and help complex reactions occur everywhere in life‚ for example a piece of steak that is being digested into energy. Molecules found at the beginning of the process are called substrates‚ and these enzymes exchange them into differing molecules known as products. Nearly all-metabolic processes in a cell need enzymes in order to function at rates that are fast enough to sustain existence. Those who are lactose intolerant are simply

and measure the enzyme activity of β-galactosidase in the different concentrations of o-Nitrophenylgalactoside (ONPG) using a spectrophotometer. The spectrophotometer was also set at 420nm‚ a wavelength which is best for recording the absorbance values for the experiment. From the results‚ 0.9mM ONPG solution has the highest absorbance and 0.1mM ONPG solution has the least. Also‚ 0.5mM ONPG solution has the highest rate of enzyme activity and it is the most efficient as the enzyme activity of the

The study aims to emphasise upon the role of HR manager and his power as “human capital” in the enterprise and hence act as a catalyst of change in an organisation. Methodology: The data have been collected through extensive literature review and past studies. Various web-sites have been explored for relevant information.

cause has yet to be found. Anti-homosexuals‚ consisting mainly of religious groups‚ believe that homosexuality is abnormal‚ unnatural‚ and can be changed. Because of their beliefs‚ homosexuality must be a learned behavior. Whether homosexuality is biological or learned behavior is still a mystery‚ but scientists are finding more evidence to suggest the former. Webster’s online dictionary defines abnormal as deviating from the normal or average. By that definition alone homosexuality is abnormal‚ but

8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules of one substrate. The site of the reaction occurs in an area on

We examined reaction rates in the presence or absence of an enzyme‚ the effects temperature and pH changes on the enzyme and the effects enzyme concentration and substrate concentration had on the enzyme. As expected results showed us that cellobiase works optimally when conditions are favorable. We see this

2. Biological Classification Classification The process of grouping living organisms into convenient categories based on simple characters is known as classification. 1. Two kingdom classification Carolus Linnaeus divided all living things into two kingdoms- Plantae and Animalia. 2. Five kingdom classification R.H. Whittaker divided all living things into five kingdoms- Monera‚ Protista‚ Fungi‚ Plantae‚ and Animalia. The main criteria for classification included o cell structure o thallus
