Title: “The Effect of Substrate Concentration‚ Enzyme Concentration‚ pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea‚ combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results.

As the temperature increased‚ the enzyme activity also increased‚ however‚ only to an optimal level which was at temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient

That is where hydrogen fuel cells come into the picture. Rather than depending on a foreign countries oil‚ to provide fuel‚ businesses today should look to hydrogen as an alternative fuel source. The United States is too dependent on foreign oil. If something were to happen‚ like another war with the Middle East‚ we would not have any oil to power our cars or heat our homes. That’s why hydrogen is the answer. Everybody could make their own fuel for their country by creating hydrogen plants and buying

homeostasis to regulate control systems such as body temperature‚ osmotic balance‚ blood pressure‚ blood glucose and respiratory gases in tissues. This report will focus on thermoregulation‚ which is the ability of an organism to keep its body temperature within certain boundaries‚ despite the fluctuating external environment. The purpose of thermoregulation is to balance thermal inputs and thermal losses in the body to maintain a core body temperature of approximately 36.7 degrees celsius‚ despite the

Discuss why hydrogen bonding is essential for life Throughout biochemistry there are many bonds without which life as it is on earth today would not be possible. One of the most important bonds of these is the hydrogen bond‚ a weak chemical bond that is present in essential biological molecules such as water and polypeptides. A hydrogen bond is defined by Campbell and Reece as occurring when a hydrogen atom is covalently bonded to an electronegative atom but attracted to another electronegative
