experiment to find the optimum temperature and pH for starch on amylase. The experiment was carried out in one day. The researcher and a partner did the experiment based on a lab manuel from class. Data was collected from the experiment and to be displayed on graphs. Then the optimum pH and temperatures were to be calculated based on the findings. The hypothesis was disproved due to the optimum pH of 5 but the other findings supported the hypothesis of the optimal temperature being 45 degrees Celsius.

To investigate the effect of temperature on an enzyme controlled reaction Introduction and planning For the investigation of enzymes‚ I am going to conduct an experiment to see how temperature can affect the rate of reaction of enzymes by testing it with starch. The enzyme that we are going to use is called amylase. We are going to test this enzyme with starch. By mixing amylase and starch solutions together under different temperature conditions‚ we can record the rate of reaction by taking a

Industrial Efficiency (1913) were written by Scott and Munsterberg‚ respectively. The methodological next step beyond Scott and Munsterberg came in 1911 when Frederick Winslow Taylor developed his theory of “Scientific Management”‚ which puts for a scientific procedure for the managing of production workers on the factory line. The field of industrial/organizational psychology took a leap in technological applicability when Frank Gilbreth‚ an engineer‚ and Lillian Gilbreth‚ a psychologists‚ combined

An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate

Abstract In this lab‚ we tested the effects of temperature on fungal amylase and bacterial amylase (Aspergillus oryzae and Bascillus Licheniformis). We used 4 different temperatures in Celsius 0‚ 23‚ 58‚ and 89 for both fungal and amylase. For 10 minutes‚ every 2 minutes we would use 3 drops of each amylase and mix it with iodine to observe the presence of starch at each temperature. We conducted this experiment for both bacterial and fungal amylase. Results were reached based on the color of the

Algae blooms are due to a rapid increase of algae and too much nitrogen in the water. From this information‚ I can deduce that there is a runoff problem from one or more of the farms where fertilizer
